How to get value of row in Gridview and display in Textbox?
Don't work this code. And I don't want to use this code:
protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e) {
LinkButton lnkButton = sender as LinkButton;
GridViewRow row = (GridViewRow) lnkButton.NamingContainer;
lblSender.Text = row.Cells[2].Text;
lblSubject.Text = row.Cells[5].Text;
txtReadMsg.Text = row.Cells[6].Text;
Are you sure your GridView's cells don't have controls inside it.
maybe this helps you
To get the row, do:
var row = GridView1.Rows[e.NewSelectedIndex];
And then the rest of the code should work for you. You can then remove the first two lines. Also, note Text only works if you are using BoundColumn column definitions; it won't work if you are using a different type of column.
If you are getting a different error, then it's related to something else; please add a comment and we can help work through it.

I have a grid view with number of pages.using check box i like to get value of selected check boxes. i have no idea to get value from selected check boxes in different pages.Please give me your suggestion and coding for this.
Use this one
protected void btnClick_Click(object sender, EventArgs e)
{
StringBuilder sbQuery = new StringBuilder();
bool flag = false;
foreach (GridViewRow row in gridview1.Rows)
{
if (((CheckBox)row.FindControl("chk")).Checked)
{
flag = true;
//------
}
}
}
As you have illustarted in question i am assuming that you want checkboxes values so i have one linke which i providing you
this will help you to understand how would you achieve and also i am recommanding you to use javascript

What I want to do is when I select the row of the data in my database, it will go to textbox. For example the data in column "Title" will go to textbox1 and the data in column "ISBN" will go to textbox2. I haven't edit any properties in Properties window of datagridview. Can someone help me?
You will have to do something like this:
yourTextBox.Text = yourDataGridView.SelectedRows[0].Cells["Title"].Value.ToString();
yourTextBox2.Text = yourDataGridView.SelectedRows[0].Cells["ISBN"].Value.ToString();
EDIT: I assume that you have selected the row on your datagrid. I´m sorry for the mistake, it was Cells property instead of Columns
Hope that helps.
You can try using the CellClick event of the DataGridView tool.
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
textbox1.Text = dataGridView1.Rows[e.RowIndex].Cells["Title"].Value.ToString();
textbox2.Text = dataGridView1.Rows[e.RowIndex].Cells["ISBN"].Value.ToString();
}
I'm trying to figure out how to get a bounded datagridview column in my c# winform project to show up like an href link. The thing is that the link click works but any average user wouldn't realize that they can click the field since it's displayed as a string. I need the field to show up as blue, with underlines, the mouse pointer turns into a hand ...etc.
I was able to accomplish this previously when I was using Datasets with my Datagrid. I went to the designer and selected "Add Column" and added it as a 'DataGridViewLinkColumn". I've recently changed the project to use datatables and I realized that the fields no longer show up as clickable (if I click it does work though).
Any ideal how to accomplish this with relative ease? I've searched and I'm somewhat surprised that I cannot seem to find a simple solution.
Change the type of the cells that are links to be a DataGridViewLinkCell and then handle the click on the cell, like this:
void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
foreach (DataGridViewRow r in dataGridView1.Rows)
{
if (System.Uri.IsWellFormedUriString(r.Cells["Links"].Value.ToString(), UriKind.Absolute))
{
r.Cells["Links"] = new DataGridViewLinkCell();
DataGridViewLinkCell c = r.Cells["Links"] as DataGridViewLinkCell;
}
}
}
// And handle the click too
private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex] is DataGridViewLinkCell)
{
System.Diagnostics.Process.Start( dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value as string);
}
}
This might help:
DataGridViewLinkColumn col1 = new DataGridViewLinkColumn();
dataGridView1.Columns.Add(col1);
dataGridView1.Columns[0].Name = "Links";
DataGridViewRow dgvr = new DataGridViewRow();
dgvr.CreateCells(dataGridView1);
DataGridViewCell linkCell = new DataGridViewLinkCell();
linkCell.Value = #"http:\\www.google.com";
dgvr.Cells[0] = linkCell;
dataGridView1.Rows.Add(dgvr);
it creates a col and then a cell of type link.
you can use foreach loops to do this more orderly and faster for more items.
Good Luck!
Take a look at the DataGridViewLinkColumn.LinkBehavior Property. It can be set to AlwaysUnderline.
As for color, simply use the *LinkColor properties on the DataGridViewLinkColumn.
Cheers
You could just colour that column in the datagridview. You could do this in a DataBindingComplete event like so:
private void dataGridView1_DataBindingComplete(object sender,
DataGridViewBindingCompleteEventArgs e)
{
if(this.mydatagridview.Columns["YourLinkColumnName"] != null)
{
this.mydatagridview.Columns["YourLinkColumnName"].DefaultCellStyle.Font = ...
this.mydatagridview.Columns["YourLinkColumnName"].DefaultCellStyle.ForeColor = ...
}
}
You can set the font to be however you like it (ie. underlined, colored, etc.).
Alternatively, you can change the default cell style in the designer if you have the columns premade (not autogeneratedcolumns).
How do you add a button to cells in a row and not the entire column in a datagridview?
I think Adrian's answer was close. Try something like this.
if ((string)table.Rows[0].Cells[0].Value == "I should be a button") {
// you can add formatting or values to the button before assigning it here
table.Rows[0].cells[0] = new DataGridViewButtonCell();
}
I think the best answer if found here:
Hide gridview button. All you need to do is to add a DataGridViewButtonCell where you want buttons, and DataGridViewTextBoxCell where you do not. The column has to be DataGridViewButton type.
See this similar post in SO, probably helps
adding control to gridview
In case Win Form, Check this MSDN post
Column Types in the Windows Forms DataGridView Control
OR this code project post ... though it gives example of adding a image button
DataGridView Image Button Cell
#tmax In that case you can probably put your button creation code in GridView_RowCreated event like below
void GridView_RowCreated(Object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.Header)
{
//Button creation code here
}
}
private void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
{
Button btn = new Button();
//btn attributes
dataGridView1.Rows[0].Cells[3].Value = new Button();
}
try something like this.
What I endded up doing was stacking a DataGridView on top of another one. I turned off the border, gridlines, and scrollbars. Then create dynamic button columns to match the main datagridview with only one row of buttons. Then I used the ColumnWidthChanged event handler to resize both the DataGridViews together. Anyway's this was my workaround for now.
DataGridViewButtonColumn dataGridViewButtonColumn = new DataGridViewButtonColumn();
dataGridViewButtonColumn.Name = "Select";
dataGridViewButtonColumn.HeaderText = "Select";
dataGridViewButtonColumn.ReadOnly = false;
dataGridView1.Columns.Add(dataGridViewButtonColumn);
After assigning data source to gridviewCTRL. you can add new column with button with below code.
DataGridViewButtonColumn startbtn = new DataGridViewButtonColumn();
startbtn.Name = "Action";
startbtn.Text = "Start";
startbtn.UseColumnTextForButtonValue=true;
int columnIndex = 6;
gridviewCTRL.Columns.Insert(columnIndex, startbtn);
This will add the button to each and every row at define column index.
if you want to render condition the AccessibleObject, then you can do something similar to below.
foreach (DataGridViewRow rowdata in gridviewCTRL.Rows)
{
// this is just an example in my case i am checking a previous column value
if (rowdata.Cells[5].Value=="XYZ")
{
rowdata.Cells[6] = new DataGridViewTextBoxCell();
}
}
This way you can dynamically render/ showing the control in the GridView in Winforms c#.
The above code simple update the cell with new cell. We can't remove button from the cell nor remove whole, so instead we can initial a new cell that will override the button visibility.
I am not sure if this will help but you can also consider using TableLayoutPanel.

Got a asp.net page which contains a
Datalist. Inside this datalist, there
is a template containing a
dropdownlist and each time the
datalist is filled with an item, a
ItemCreatedCommand is called. The
itemCreatedCommand is responsible for
databinding the dropdownlist.
I think the problem lies here, that
I'm using ItemCreatedCommand to
populate it - but the strange things
is that if I choose the color "green",
the page will autopostback, and I will
see that the dropdown is still on the
color green, but when trying to use
it's SelectedIndex, I always get 0...
protected void DataListProducts_ItemCreatedCommand(object
source, DataListItemEventArgs e)
var itemId = (String)DataListProducts.DataKeys[e.Item.ItemIndex];
var item = itemBLL.GetFullItem(itemId);
var DropDownListColor = (DropDownList)e.Item.FindControl("DropDownListColor");
//Also tried with :
//if(!isPostBack) {
DropDownListColor.DataSource = item.ColorList;
DropDownList.Color.Databind();
// } End !isPostBack)
Label1.test = DropDownListColor.SelectedIndex.toString();
// <- THIS IS ALWAYS 0! *grr*
I've narrowed down the code a bit for
viewing, but still you can see what
I'm trying to do :) The reason for
why I'm doing this, and not declaring
the datasource for the colors directly
i aspx-page, is that I need to run a
test if(showColors), but I do not want
to clutter up the html-page with code
that I feel should be in the code
behind-file.
EDIT: After trying to alter
SelectedIndexChange - I'm having a
"logical" confusion in my head now -
how am I to alter elements inside the
datalist? Since, as far as I know - I
do not have any way to check which of
the items in the datalist this
particular dropdownlist belongs to...
Or? I'm going to try out a few ways
and see what I end up with ;) But do
please post your thoughts on this
question :)
SOLUTION:
Either bubble the event to ItemCommand, or Handle the event, get the senders parent(which is a datalistItem and manipulate elements in there.
protected void DropDownListColor_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList dropDownListColor = (DropDownList)sender;
DataListItem dataListItem = (DataListItem)dropDownListColor.Parent;
var item = items[dataListItem.ItemIndex];
var color = item.ItemColor[dropDownListColor.SelectedIndex];
var LabelPrice = (Label)dataListItem.FindControl("LabelPrice");
LabelPrice.Text = color.Price;
}
When the DataList is data-bound, the AutoPostBack has not been handled yet, i.e. the values in the ItemCreated event are still the original values.
You need to handle the SelectedIndexChange event of the dropdown control.
Regarding your 2nd question:
I suggest you remove the AutoPostBack from the dropdown, add an "Update" button, and update the data in the button Click event.
The button can hold Command and CommandArgument values, so it's easy to associate with a database record.
