Forms Data Controls :: Changing Order Of Gridview Select Event
Mar 19, 2010
What I have is a command column with 2 link buttons, Review and Update. The Review link will show a more in depth look at the record (pretty much a detailsview) The Update link will allow the user to edit a few select fields. The Update link works fine, because I put the code in the GridView3_SelectedIndexChanged event. When I click the Review link (which has code in the LinkButton1_Click event), there is no data from the Selected row, because the row is not yet selected. Is there a way to trigger the selection BEFORE the button click event? It seems like this should be easy, but I haven't needed to do this before.

I have parent gridview5 and nested child gridview6 within it. The page is working as expected and formatted as i need it now.. I added a select button to the child gridview6 and when i click on it i get an error: {"Object reference not set to an instance of an object."}
I found examples of using the find control, but within the parent gridview.. and i use that fine with other controls.. but cant figure out the right combination of finding the selected row for the nested gridview so that i can display a modalpopup.

I have a grid view which is populating with a data source through databind. And the Datasource is list of objects.Now when the user selected a row I want to get the object of that row. I'm trying to get the row like this.

DataRowView
drv = r.DataItem
as
DataRowView
;
but the drv value is null. Could any body tell me how to get the object of the selected row?

How is it possible to change the displayed order of columns from a DataTable?
For example, dataTable "dt" contains two columns "a" and "b". I bind it to a GridView like this:
gridView.DataSource = dt;
gridView.DataBind();
But I'd like the GridView to display "b" first (leftmost).
Important point: I'm using this to export to Excel and there's no actual output to screen, using:
HtmlTextWriter htw = new HtmlTextWriter(sw);
gridView.RenderControl(htw);

I have gridview. some columns are data, and some are link buttons. now, I need move these link buttons to a hovermenu. this is done. but I got a javascript exception, and it is because if there is no row was selected in gridview, it will pop this.
so, the question is: how can I select a row in gridview without select command? simply by code?

I've only been coding .net for a few months so fogive me if the answer to this is obvious.I have been hitting a repeated problem in my application to do with event order.My requirement is always the same:1. Display page with controls2. Pick up on some event with these controls3. based on that event do some calculations before displaying the next page4. Now display the next page taking into account what the user has clicked.One example is that I have a chart, and next to it several link buttons these filter the age of the x axis eg 1 Year, 2 Years, 3 years. On the click event I set a from date of 12 months, 24 months or 36 months. I then display my chart initialising it in the page load event. I have a number of other things going on in the pageload making it difficult to move all the code to the control event from page-load.Neither of the above senerios work and I assume this is because the page load / init events fires before the control events from the previous page (is this right?)To illustrate the point I have made a simple program below that does not work. I'd be grateful for any guidance on how to go about this type of interface.

I have a gridview that I am using to host some data. Each row in the gridview links to a blob and I am using the SOnRowCommand event to click on the row and to stream the blob(which is an image) out as a file. This works fine. However when i implement paging on the gridview with the paging event the handler think it is an OnRowCommand event and executes the code behing the OnRowCommand handler and not the pageindex change event.
[Code]....
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
DataTable dt = new DataTable();
dt = (DataTable)Session["data"];
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataSource = dt;
GridView1.DataBind();
}

I know that variations of this same question have been posed numerous times - but I can't quite seem to find the exact solution.
I would like any row in my gridview where the boolean field "Approved" is True to be shaded gray. Here is the code that I'm using, but every row ends up being gray, regardless of the value in that "Approved" field. My guess is that I'm not correctly evaluating the boolean value in this field (which is actually a yes/no field in MS Access), Not sure if I should be reading that value as "-1", "Yes" or "True" or "NotNull"? Anyway, here is the code:

I have a DropDownList inside the EditTemplateItem (if the user clicks edit) in a GridView.The DropDownList receives all available rows from the database. My problem is,if the user clicks Edit in the GridView to edit a row and opens the DropDownList Box the original item is not selected but the first one.That means the items are sorted. Have someone an idea how I can solve this issue that the right item / the original is selected if I change to edit mode of the grid view?
