Datagrid is in content,When trying to access client side function for the cells in the datagrid,its always showing at 0 position suppose i have 10 rows,for each row "Test button" i should invoke the client side java script. For each row "Test button" client side script is displaying message at first row only.
in datagrid i am binding the description and button to every row in datagrid
so i have added Testbutton.attributes.add("onclick","return javascriptfunction();"); in datagrid_itembound.Iam showing one div in client side function but that is working only for one row,when iam trying to click test button in second row,itsshowing that div in first row instead of second row
i want similar functunality like displaying of flag button in stackoverflow.
I'm having a weird problem where the GridView cell that I'm programmatically updating turns grey, and throws a null error when attempting to save row. I have been searching all day and have not been able to find a solution. I'm guessing there is a problem with my code, so here it is:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
I have <span> tags in the cells of my datagrid which determine which background color to use. I also want the user to be able to click any cell and highlight the entire row. This works anywhere there's not a span tag. The span tag is somehow canceling this out. What would you do so that fields inside a span tag act like regular fields where you can click on them and the entire row is highlighted?

I have a datagrid whose columns are autogenerated (based on the results from an SQL SELECT query). However, I need to retrieve values from certain cells across the datagrid, using the following code to step through the results.

I need to specify all my columns using TemplateField?
is it possible to disable sorting on specific columns? 5 out of 7 columns have to be sortable, two not sortable. The columns are created dynamically in code behind, so I think doing this with mark up is out of the question. When I say disabled, I'm hoping that the underline wont show on the column header when you mouse over it.

View 2 RepliesHow to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.
[code]....
I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.
I want to populate GridView below with images:
<asp:GridView ID="GrdDynamic" runat="server" AutoGenerateColumns="False">
<Columns>
</Columns>
</asp:GridView>
The code below iterates through directory, then I collect image titles and want them to be populated in gridview. code in bold is not working well, gridview is only filled with the last image in list.
how to fill gridview cell-by-cell only with available amount of images?

Object reference not set to an instance of an object. when I try to access these dynamically created controls using FindControl.
I have a dynamically created control within a table cell. The table itself is contained within a page that has a master page. I've tried so many different ways to access this control.
Below is the latest iteration
AttrTable is the asp table, and row.Attr_Type is the name I've given to the control (it iterates through a datatable to set the names for the control)
tmpVal = CType(AttrTable.FindControl("TD_" & row.Attr_Type).FindControl(row.Attr_Type), DropDownList).Text
Below are various ways I've tried to access the control:
Dim form As Control = Page.Master.FindControl("form1")
Dim content1 = form.FindControl("ContentPlaceHolder1")
