Forms Data Controls :: Keeping Custom Properties In GridView Added On OnRowDataBound Event While Sorting

Sep 14, 2010

All of my columns are bound in the Gridview. On OnRowDataBound event, I am adding some custom styles like underlines and colors to the text of the columns. Sorting of data is working fine but I am losing my custom styles when I sort. I am using the generic sorting code for the GridView.

How I can keep my custom styles on sorting that I added during OnRowDataBound event.

Forms Data Controls :: GridView And DropDownList In ItemTemplate Column?

Dec 3, 2010

What I have is a GridView with a DropDownList in an ItemTemplate (not an EditItemTemplate). My datasource is not a control, rather in the code-behind.


My main problem is that VS is not seeing that I have the dropdownlist, meaning I can not access any of the events in the code-behind. What I want to do is, when the value of the DropDownList is changed (SelectedIndexChanged), I want to grab the value of the RowIndex of the GridView.

Forms Data Controls :: GridView PageSize And ItemTemplate Button Event Conflict?

Jul 30, 2010

GridView bound to a SqlDataSource. GridView.AllowPaging is True. In one of the ItemTemplates I have a LinkButton with a OnClick event.Have a DropDownList for changing GridView.PageSize - done in Page_LoadEverything in of-course in an UpdatePanel.

The whole thing work fine (we are in test fase). The problem is that the LinkButton OnClick event is only being attached to the initial "PageSize" amount of elements. Fx. if I sat PageSize=15 in the <asp:GridView> then change the page size to say 30 from the DropDownList, the page size changes but only the first 15 LinkButtons fire the OnClick event when clicked.

I've tried to do the following:

Attached an "onchange" javascript client event for saving the selected value in a <asp:HiddenField> before postback. Problem here is that the HiddenField value is then only available on Page_Load. By then it's too late to set the new page size on the GridView because the attachemnt of events to the LinkButtons have allready happened - of-course only to the first 15 elements.Then I tried to drop the PageSize=15 in the <asp:GridView> and only sat it in the Page_load. The idea was that with no paging all the Linkbuttons will get treated evenly. That worked, but when I change the GridView page size and click fx. on LinkButton 25, the Click event forks fine but the GridView page size resets to the initial value (15) - no good.

how I can get all the LinkButtons to have their event working, even after I change GridView page size?

Data Controls :: Populating DropDownList In Edit ItemTemplate Of GridView?

Aug 29, 2013

I read your article on ASPSnippets and everything worked great.  I am having one problem and this is preventing me from moving forward.  When I select the edit for a row (I only have two columns), the drop down comes back blank (no records).  I have looked at the code multiple times and can't see where I made a mistake. is it possible to control the width of the drop down list?  I can't tell if the column automatically adjusts because I am not returning any records.

using System.Collections.Generic;

GridView Doesn't Contain Control Added In OnRowDataBound?

Nov 9, 2010

I can't get control which I added in DataGrid. I am adding it in OnRowDataBound event like:

protected void RowDataBound(object sender, GridViewRowEventArgs e)
if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState == (DataControlRowState.Alternate | DataControlRowState.Edit))

//int cindex = 0;
//for (cindex = 0; cindex < e.Row.Controls.Count; cindex++)
foreach (Control ctl in e.Row.Controls)
DataControlFieldCell dcctl = (DataControlFieldCell)ctl;
TableCell tcell = (TableCell)dcctl;
Label lblComment = new Label();
TextBox txtComment = new TextBox();
lblComment.Text = "<br>Comment: ";

What is happening here: there is already exist one TextBox in TableCell by default and I want to add another one TextBox and Label. After the bounding I can see 2 textboxes, I can input data into the both, but when I click Update button, then raises OnRowUpdating event where I can't get my TextBox!

protected void RowUpdating(object sender, GridViewUpdateEventArgs e)
grdView.EditIndex = -1;
int counter = 0;
for (counter = 0; counter < grdView.Rows[e.RowIndex].Cells.Count; counter++)
foreach (Control ctl in grdView.Rows[e.RowIndex].Cells[counter].Controls)

And here I will be getting only default one TextBox (with its value). But my TextBox is disappeared! :(

P.S. I can't use predifined columns, like asp:TemplateField in aspx file, because my table has different amount of rows every time. It is dynamic

Web Forms :: DropDownList In ListView ItemTemplate?

Jul 11, 2010

I have various difficulties handling dropdownlist in listview itemtemplate.Hopefully, resolving this example will help me understand how to make things work.I need to do several things upon DropDownList1_SelectedIndexChanged.(1) Fetch row index of listview then set the row as listview selected, or vice versa, in which dropdownlist was changed.(2) Fetch text of namelabel in that selected listview row.(3) Fetch selected text of dropdownlist in that selected listview row.


At the moment...(1) Label1.Text = ListView1.SelectedIndex always shows '-1' regardless in which row dropdownlist is selected/changed.(2) Label2.Text = NL.Text pops 'Object reference not set to an instance of an object'.(3) Label3.Text = DDL1.SelectedItem.Text pops 'Object reference not set to an instance of an object'.
