When I edit the grid shows me the following error.

I'm trying to create as many columns as there are data in thedatabase. And the only way I can create the template editing is by using the "autogenerated"

But whenever I have the same problem. I've tried so many ways to fix it but I can not think of anything.

All columns are inserted from C# code. The reason is that thenumber of columns depends on the number of fields in thedatabase.

Downloading from Grid problem

Hi,

I am new to telerik controls. It seems really good an I have been evaluating it for use in a project I am working on. The client is really impressed with the look/feel/design. But before I can get him to purchase it I need to be sure I can achieve all the results needed. There is only 1 problem, I am unable to get downloads from a grid working. Below is the code I am using to run the download command. The problem is the choose location dialogue box never appear when I click the download link. I need to mention here that the download link is in a nested grid (grid inside a master grid). Could this be the problem? How do I overcome this?

//Code for inner grid. The event is grid_itemcommand()
void gvReceipt_ItemCommand(object source, GridCommandEventArgs e)
   {
   if (e.CommandName == "Download")
   {
   var ExpHeader_ID = (int)((GridEditableItem)e.Item).GetDataKeyValue("ExpenseHeaderID");
   Int32 ExpID = Convert.ToInt32(ExpHeader_ID);
   ExpHeaderIdReceipt = ExpID;

   GridDataItem dataItem = (GridDataItem)e.Item;
   Label lblImgeName = (Label)dataItem.FindControl("lblImage");
   string strRequest = lblImgeName.Text;
   if (!string.IsNullOrEmpty(strRequest))
   {
   string path = Server.MapPath(Manage_FilePaths.HeaderExpImagesRootPath_Original
+ strRequest);
   System.IO.FileInfo file = new System.IO.FileInfo(path);

   if (file.Exists)
   {
   Response.Clear();
   Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
   Response.AddHeader("Content-Length", file.Length.ToString());
   Response.ContentType = "application/octet-stream";
   Response.WriteFile(file.FullName);
   Response.End();
   }
   else
   {
   Response.Write("This file does not exist.");
   }
   }
   else
   {
   ScriptManager.RegisterStartupScript(this.updGrids, typeof(string), "alert", "<script>alert('Please provide a file to download!');</script>", false);
   }
   }
   }

Iterate through Yaxis Major tick labels?

Is there a way to change the value of Yaxis major tick labels once the graph is established?

I am passing -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5 for the Y axis. Client wants all values to show as positive, but respecting the negative position 5, 4, 3, 2, 1, 0, 1, 2, 3, 4, 5 on the same Y axis.

Is there a way to step through axis labels and if the value is less than 1, multiply by -1, or just abs() all the ticks?

Over effect only in master table

In a hierarchical grid, how can I get the over effect in only master table but NOT in detail table?

How do you catch a GroupByExpressions Error?

Hi,
I'm creating a GroupBy expression dynamically based on user input:

RadGrid1.MasterTableView.GroupByExpressions.Add(txtUserInput.Text);

Occasionally the user gets this wrong which causes an error.
I simply want to catch this error in a try/catch block and handle it, but I'm not sure where to put the try/catch.
Any help would be appreciated.
Thanks,
Nick

How to modify the css of the GroupHeader?

Hi.
I am migrating a former asp:grid, and since some features must remain the same (or as close to it as possible), the style of the GroupHeader should be similar to the former.
I need to find a way to change de color and size of the text of the GroupHeader:

<SelectFields>

<telerik:GridGroupByField FieldAlias="My Group Description" FieldName="MyField"></telerik:GridGroupByField>

</SelectFields>

Is there any avaiable property to perform such a customization? And if there's none, can I do it by changing the CSS (even if it means creating a custom grid css file)?

Many thanks in advance.

How to not select text in a grid?

is there a way to not highlight the text in a grid when the user selects or drags with their mouse in a grid? I've attached a screen shot of what it is doing currently. We have other grids on our site that don't allow this behavior but I cannot figure out how that is possible.

Thanks,

Jon
