I tried to get the control of edit template which is checkbox in row command event but I am unable to get it, but I am getting label control which is in row index.
I tried the above below code to get the control:
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
GridViewRow gvr = (GridViewRow)(((ImageButton)e.CommandSource).NamingContainer);
Label icllbl = (Label)GridView1.Rows[gvr.RowIndex].FindControl("icllbl");
CheckBox iclcb = (CheckBox)GridView1.Rows[gvr.RowIndex].FindControl("iclcb");
if (e.CommandName.Equals("Edit"))
{
if (icllbl.Text == "Y")
{
iclcb.Checked = true;
}
}
}
And I tried RowDataBound event also luckily I am getting checkbox control here but this time I am unable to get the Label control in below code:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label icllbl = (Label)e.Row.FindControl("icllbl");
if ((e.Row.RowState & DataControlRowState.Edit) > 0)
{
CheckBox iclcb = (CheckBox)e.Row.FindControl("iclcb");
if (icllbl.Text == "Y")
{
iclcb.Checked = true;
}
}
}
}
Please correct me if I am wrong anywhere.
Thanks in advance!
In your RowCommand event use control class to cast into GridViewRow:
GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer);
int rowIndex = row.RowIndex;
And in RowDataBound event place Label control inside Edit (check for EditTemplate) check:
if ((e.Row.RowState & DataControlRowState.Edit) > 0)
{
Label icllbl = (Label)e.Row.FindControl("icllbl");
CheckBox iclcb = (CheckBox)e.Row.FindControl("iclcb");
//... other code of lines will be here
}

I am able to add unlimited textbox column in a row of gridview. but after postback these textboxes get disposed. So how to retain these textboxes and their values after postback?
Code:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
int i = 3;
if (e.Row.RowType == DataControlRowType.DataRow)
{
crcl = (List<string>)ViewState["bdi2"];
foreach(string a in crcl)
{
TextBox TextBox101 = new TextBox();
TextBox101.ID=a;
TextBox101.Width = 60;
TextBox101.Text = (e.Row.DataItem as DataRowView).Row[a].ToString();
e.Row.Cells[i].Controls.Add(TextBox101);
//TextBox101.AutoPostBack = true;
i++;
}
}
}

Below is my code behind:
public void enableEditMedChange(object sender, GridViewEditEventArgs e)
{
MedChangeTable.EditIndex = e.NewEditIndex;
}
protected void MedChangeTable_RowDataBound(object sender, GridViewRowEventArgs e)
{
using (DeveloprodDataClassDataContext adminDB = new DeveloprodDataClassDataContext())
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if ((e.Row.RowState & DataControlRowState.Edit) > 0)
{
DropDownList newMedChangeChangeDD = (DropDownList)e.Row.FindControl("NewMedChangeChangeDD");
newMedChangeChangeDD.SelectedValue = ???
}
}
}
}
I would like to set the drop down's selected value to whatever value was in one of the cells in the row who's edit button was clicked on. How can I pass along this value to the row data bound event?
You can get the value like this:
DropDownList newMedChangeChangeDD = (DropDownList)e.Row.FindControl("NewMedChangeChangeDD");
newMedChangeChangeDD.SelectedValue = DataBinder.Eval(e.Row.DataItem, "YourDataFieldName").ToString();

protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
**if (e.Row.RowIndex >= gridview1.PageSize) // ROW FOOTER TOTAL**
{
e.Row.BackColor = System.Drawing.Color.Firebrick;
e.Row.ForeColor = System.Drawing.Color.White;
}
}
This code works sometimes, someone can help me
DM,cheers
You can try to find the last column in the PreRender event
protected void grid_PreRender(object sender, EventArgs e)
{
GridViewRow row = grdAlert.Rows[grdAlert.Rows.Count - 1];
// do stuff with your row
}
If you just need to change the style of the footer you can use
<asp:GridView ID="grid" runat="server" FooterStyle="your style"></asp:GridView>
A grid view doesn't appear to have a row count until it's finished binding each row. So, another thought:
Can you determine the number of rows from the datatable that the gridview is binding to, then store that in a variable for use later?
you can find last row like this
GridViewRow row = GridView1.Rows[GridView1.Rows.Count-1];
or use this
protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
GridView grid = (GridView)sender;
if(e.Row.RowIndex == (grid.Rows.Count - 1))
{
//last row
}
}
}
It seems that you want to detect the footer row in RowDataBound since you have commented //ROW FOOTER TOTAL, you just have to check for the DataControlRowType.Footer:
protected void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Footer)
{
// here it is
}
}
Otherwise you could compare the RowIndex with the row of the undrlying DataItem:
DataRowView row = (DataRowView)e.Row.DataItem;
if (e.Row.RowIndex == row.DataView.Count - 1) ; // last row
In your page load method set colors as below
protected void Page_Load(object sender, EventArgs e)
{
//code what you currently have ....
// add below code after that
GridViewRow row = GridView1.Rows.Count-1;
row.BackColor = System.Drawing.Color.Firebrick;
row.ForeColor = System.Drawing.Color.White;
}
I have a gridview which checks some values on rowDataBound event.I want to remove some rows based on conditions checked in rowDataBound.I tried putting all controls in a Panel and hiding that panel ie,
TRY 1 :
protected void grdFeatured_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
//some other codes here
//IMPLEMENT FILTER ACCORDING TO ABOVE 'VIS' OUTPUT
if (vis > 0)
{
Panel1.Visible = false;
}
}
}
PROBLEM :
This messes up the paging since rows are hidden but page count occurs and shows page numbers for the remaining visible rows.
TRY 2 :
protected void grdFeatured_RowDataBound(object sender, GridViewRowEventArgs e)
{
GridViewRow gvr = e.Row;
if (e.Row.RowType == DataControlRowType.DataRow)
{
//some other codes here
//IMPLEMENT FILTER ACCORDING TO ABOVE 'VIS' OUTPUT
if (vis > 0)
{
gvr.Parent.Controls.RemoveAt(gvr.RowIndex);
}
}
}
PROBLEM :
gives error :
Specified argument was out of the range of valid values.
Parameter name: index at gvr.Parent.Controls.RemoveAt(gvr.RowIndex);
dont want to edit datasource, help me out guys .
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (somecondition)
{
e.Row.Visible = false;
}
}
I want to get the value of a CheckBox in a GridView. I'm able to bind the GridView using the event RowDataBound. But on a Click event of a Button the value of the CheckBox is always false even if I checked the CheckBox.
Code Behind:
protected void GridView1_RowDatabound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList dddate = (DropDownList)e.Row.FindControl("DdlDate");
DropDownList ddYear = (DropDownList)e.Row.FindControl("DdlYear");
for (int i = System.DateTime.Now.Year; i > (System.DateTime.Now.Year) - 100; i--)
ddYear.Items.Add(Convert.ToString(i));
for (int i = 1; i < 32; i++)
dddate.Items.Add(Convert.ToString(i));
}
}
protected void btnRetrieveCheck_Click(object sender, EventArgs e)
{
foreach (GridViewRow row in GridView1.Rows)
{
CheckBox cb = (CheckBox)row.FindControl("chkSel");
if (cb != null && cb.Checked)
{
DropDownList dddate = (DropDownList)row.FindControl("DdlDate"); //Bind data to the GridView control.
DropDownList ddYear = (DropDownList)row.FindControl("DdlYear");
DropDownList ddmonth = (DropDownList)row.FindControl("DdlMonth");
}
}
}
You should hook up to the Checked event on the checkbox instead of the click event.
Your question is not very clear. Can you post some more of the code. For example, what is btnRetrieveCheck - is it the actual checkbox? Please update the question with your XAML so we can see what binding is in place.
