I want to fill textboxes when a user clicks on a row. I don't want to use grdUser..SelectedRow.Cells[1].Text because my datagrid has a summary of the user details e.g. name, SSNumber, email. if I click on the row then I want all the user details should load into textboxes. How would I do that?
I would like to use a sql query but then my where clause should use SSNumber but not sure that's best practise.
C# or vb help welcome.
You can add Attributes to the Row created and when the user clicks that row redirect them to a page with the Id of the object you want to display. I know you are using a datagrid my example is using a GridView
For example on Row created
protected void ListGrid_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType .DataRow)
{
e.Row.Attributes[ "onmouseover"] = "this.style.cursor='pointer';this.style.textDecoration='underline';" ;
e.Row.Attributes[ "onmouseout"] = "this.style.textDecoration='none';" ;
e.Row.ToolTip = "Click to select row";
e.Row.Attributes[ "onclick"] = "Javascript:window.location = '" + ResolveClientUrl("~/PickList/ScanPickListItem.aspx" ) + "?PLRID=" + DataBinder.Eval(e.Row.DataItem, "ScreenRowId" ) + "'";
}
}
First, get the index of the selected row then get the value of the specific cell
Dim dgv_active_Row as Integer= dgv.CurrentRow.Index
TextBox1.Text = dgv.Item(1, dgv_active_Row).Value
'1' is the index of the specific column where you want to get the value of the textbox

I want to load data from a row that when selected by means of a button loads them into a format. For this I am doing with the CommandName, as if they were coordinates, clicking on such a row will load this data and so on for all. But I do not know how to do it in rows and cells with textbox.
I did so like it's in the code but I do not know if it's fine.
Where you have two dashed lines is how I wrote it for the Textbox.
In the form (format) I have Textbox and there should automatically appear the data when selecting any row.
if (e.CommandName.ToString() == "clic") {
//DETERMINING THE INDEX OF THE SELECTED ROW
int indexrow = int.Parse(e.CommandArgument.ToString());
int id = (int)this.gridview.DataKeys[indexrow]["Id"];
-- TextBox1.Text = gridview.Rows[indexrow].Cells[2].ToString();
This is how you accomplish what you want (I think). But in your question I don't see a TextBox present in the GridView.
if (e.CommandName.ToString() == "clic")
{
//cast the container of the sender back to a gridviewrow
GridViewRow row = (GridViewRow)((Control)e.CommandSource).NamingContainer;
//get the row number
int indexrow = row.RowIndex;
//get the value of cell 2 in the textbox
TextBox1.Text = gridview.Rows[indexrow].Cells[2].Text;
}
If you mean to use "Edit" mode in the GridView with EditItemTemplate, then have a look at this tutorial.
I would like to search my DataSet for a customer name, this name will occur more than once throughout the dataset, meaning there will be more than 1 result (multiple rows returned)
When my search button is clicked, form2 opens up, and in theory should display all rows containing the customer name, but how do I achive this?
I can get it to display 1 row without a problem, but how would I make it display all rows, and the data in textboxes.
At the moment I am using a foreach loop to fill text boxes with returned data, but this only takes data from 1 row within my DataSet.
Is there a way I can make my form auto generate textboxes and populate them will all the data from the array? When I run my query at the moment, it fills the textboxes on form2 with the last rotation of the foreach.
DB Sample
Appreciate any help
Adam
DataRow[] returnedRows;
returnedRows = ds.Tables["Table_Data_1"].Select("cust_name='" + searchFor + "'");
foreach (DataRow returned in returnedRows)
{
tbName.Text = returned[1].ToString();
tbAddress.Text = returned[2].ToString();
tbPhone.Text = returned[3].ToString();
tbMake.Text = returned[4].ToString();
tbModel.Text = returned[5].ToString();
tbReg.Text = returned[6].ToString();
tbYear.Text = returned[7].ToString();
tbParts1.Text = returned[8].ToString();
tbParts2.Text = returned[9].ToString();
tbParts3.Text = returned[10].ToString();
tbParts3.Text = returned[11].ToString();
}
The reason you're having just a single value appear is that you're setting the text of your text boxes to a new value for each row that you've selected. You could change your code to instead add to the Text in the the Textboxes:
tbName.Text += returned[1].ToString() + Environment.NewLine;
Or you could instead bind it to a DataGridView, which is designed to display tabular data. Assuming the DataGridView was named something like customerDataView,
returnedRows = ds.Tables["Table_Data_1"].Select("cust_name='" + searchFor + "'");
var newTable = returnedRows.CopyToDataTable();
BindingSource bindSource = new BindingSource();
bindSource.DataSource = newTable;
var customerDataView.DataSource = bindSource;
You can generate textboxes dinamicaly
Its something like this
foreach (DataRow returned in returnedRows)
{
TextBox txt = new TextBox();
txt.ID = "textBox1"; //generate id dinamically can be a count
txt.Text = returned[1].ToString();
form1.Controls.Add(txt);
}
The way you've implemented the loop override the data in each interation
I've improved the sample code from following this post

I am trying to import csv to mssql using c# code on a asp.net application.
the below c# code helps to load the csv file, choose the table to import to
and then a button click event matches columns and populates a gridview (dgvmatchdata)
the gridview has two columns where the left side column lists all the available table headers from db
and right side column lists all the csv headers in a drop down list.
now, there are 3 conditions
1. both table and csv has equal no. of column headers.
2. table has more columns than csv
3. csv has more columns than table.
i have successfully finished the first two scenarios. and now, i am stuck at the 3rd scenario
my approach to this is,
for example lets consider the table as 10 columns and csv has 15 columns.
i wish to create 15 rows in dgvmatchdata and display the 10 table column headers on the left side
on their own labels for each. the equivalent righ side of the dgvmatchdata will have a drop down list
which contains 'ignore this column' + 15 columns headers from the csv. so, the ddl will now have 16 items.
i want to place text box for the remaining 5 rows on the table column side and i want to populate
the text box with dropdown list. selected items.text during dropdown selected item change event.
now after i have successfully got text inside the remaining 5 text boxes i will write a code on a button click event
to alter table in the db and then the next step would simply import the csv data to the altered table flawlessly.
the point where i am seeking help is, i have placed the text box correctly but the text box disappears on ddl.selecteditem changed
due to post back issue and i am unable to get the text inside the text box.
kindly help.
Gridview Code
protected void dgvmatchdata_RowDataBound(object sender, GridViewRowEventArgs e)
{
DataTable dt = (DataTable)Session["importcsv"];
string[] csvcolNames = (from dc in dt.Columns.Cast<DataColumn>() select dc.ColumnName).ToArray();
string tablename = ddltable2.SelectedItem.Text;
string[] dbcolNames = loadDataBaseColumns(tablename);
int dbcol = dbcolNames.Length;
int csvcol = csvcolNames.Length;
if (e.Row.RowType == DataControlRowType.DataRow)
{
//Find the DropDownList in the Row
DropDownList ddlcsvcolumns = (e.Row.FindControl("ddlcsvcolumns") as DropDownList);
ddlcsvcolumns.DataSource = csvcolNames;
ddlcsvcolumns.DataBind();
ddlcsvcolumns.Items.Insert(0, new ListItem("Please select"));
}
for (int i = 0; i < dgvmatchdata.Rows.Count; i++)
{
DropDownList ddlselect = dgvmatchdata.Rows[i].FindControl("ddlcsvcolumns") as DropDownList;
foreach (string col in csvcolNames)
{
string tablcol = ((Label)dgvmatchdata.Rows[i].FindControl("lblcolumns1")).Text;
if (tablcol == col)
{
ddlselect.SelectedItem.Text = col;
ddlselect.Enabled = false;
dgvmatchdata.Rows[i].Cells[1].BackColor = System.Drawing.Color.SpringGreen;
}
}
}
}
Drop Down Selected Index Changed
protected void ddlcsvcolumns_SelectedIndexChanged(object sender, EventArgs e)
{
for (int i = 0; i < dgvmatchdata.Rows.Count; i++)
{
string selectcolumns = ((DropDownList)dgvmatchdata.Rows[i].FindControl("ddlcsvcolumns")).SelectedItem.Text;
Label selectlabel = (dgvmatchdata.Rows[i].FindControl("lblColumns") as Label);
TextBox txtcol = (TextBox)dgvmatchdata.Rows[i].FindControl("txtDynamicText" + i.ToString());
if (selectcolumns.Equals("Please select"))
{
selectlabel.Text = "";
}
else
{
selectlabel.Text = selectcolumns;
}
}
}
I know how to to do it and put the data on textbox when I select a row from a gridview, What I want to achieve now is when I open a modal pop up form containing a gridview, it will automatically select or extract the date column from the last row of gridview.
This is for the purpose of determining the last date from the record.
Here's what I got so far (under click event for button "ADD")
if (grdSpecificTenantRental.Rows.Count == 0)
{
txtdatefrom.Text = "No record yet";
}
else
{
GridViewRow rowtwo = grdSpecificTenantRental.Rows[grdSpecificTenantRental.Rows.Count - 1];
string index = rowtwo.Cells.ToString();
txtdatefrom.Text = index;
}
Here's the output int he textbox: System.Web.UI.WebControls.TableCellCollection
Obviously this line is incorrect: string index = rowtwo.Cells.ToString();
I want to extract the 4th column in the last row which is the end date
Currently you are getting all the cells that is CellCollection so if you want to get perticular column value then use that array's index to get the required columns value.As you mentioned 4th columns so use the index 3 because index starts from 0.You might want to access it like this,
txtDateFrom.Text = grdSpecificTenantRental.Rows[grdSpecificTenantRental.Rows.Count - 1].Cells[3].Text;
I have a DataGridView with 4 columns.
When a user double clicks the row, I want to revtrieve data from the 1st column of the clicked row.
private void ticketsDataGridView_CellMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e)
{
MessageBox.Show("Row " + e.RowIndex); // gets me the row selected
}
How can I get the column for the selected row?
Look at DataGridView.Rows Property
try this on doublic click event.
DataGridViewRow row =dataGridView.Rows[0];
string someStringColumnValue = (string)row.Cells[0].Value;
