Setting SelectedIndexChanged event server side

I have a combobox in a grid popup edit form that I'm creating programatically and I'm trying to set the SelectedIndexChanged event, but I can't seem to get it to fire.

there are some data points that get read in to determine whether or not to set the SelectedIndexChanged event, but here is the code

if (optionType == "ComboBox")

{

RadComboBox combo = new RadComboBox();

combo.ID = "dd_" + option.ToString();

combo.Font.Size = 8;

if (optionName == "Report Date")

{

combo.AutoPostBack = true;

combo.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(dd_RptDate_SelectedIndexChanged);

}

foreach (var optionValue in q_optionValues)

{

combo.Items.Add(new RadComboBoxItem(optionValue.tReportOptionValue.OptNm, optionValue.tReportOptionValue.OptVal));

// if option is Report Date, determine additional controls depending on dropdown value

if (optionName == "Report Date")

{

//if optionvalue is specific date, set the datepickers bool to true

if (optionValue.tReportOptionValue.OptNm == "Specific Date")

{

datepickers = true;

}

//if optionvalue is specific months, set the monthpickers bool to true

if (optionValue.tReportOptionValue.OptNm == "Specific Months")

{

//datepickers = true;

}

panelContent.Controls.Add(combo);

}

I know I'm getting to the point where it should assign the SelectedIndexChanged event because the AutoPostBack attribute right above it is working (I can comment out that line and the combobox doesn't postback).

Here is the associated event code

protected void dd_RptDate_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

{

string url = "/";

Response.Redirect(url);

RadComboBox combo = (RadComboBox)sender;

GridEditFormInsertItem editFormItem = (GridEditFormInsertItem)combo.NamingContainer;

BuildOptions(editFormItem);

}

I put in the Response.Redirect just to see if the event was firing and it's not.

Am I not going about this correct way? I need to be able to fire off this event so the BuildOptions event gets run when the postback occurs.

Thanks

Problem Implementing Master / Child RadGrids

Hello, I am attempting to implement a series of Master / Child RadGrids, similar to the example located:

http://demos.telerik.com/aspnet-ajax/grid/examples/programming/selectedvalue/defaultcs.aspx

In fact, I copied most of this code and modified it to work with my database structure.

The problem I have is as follows:

When clicking on a row in Grid #1 to select it, the child Grids #2 and #3 update correctly to reflect the appropriate data associated with Grids #1 and #2, respectively

However, when I use the Next/Previous buttons located in Grid #1 to move between records, only the data in Grid #2 updates. The data in Grid#3 never updates.

The online example posted above exhibits the same behavior. At first I thought that I did something wrong in my program, and have been wracking my brains for a day trying to figure out what I did wrong. Only after I went back to the online example did I see the online example exhibits the same behavior. You can see for yourself... if you go to the example, and click on one of the rows in Grid #1, the data in Grids #2/3 will update... but if you click on the nav buttons in Grid #1, only Grid #2 updates, Grid#3 remains unchanged.

Two questions:

a. Is this a bug in the control, and

b. How can I get Child Grid #3 to update correctly from Grid #2's key value when the user clicks a navigation button on Master Grid #1?

Grid Paging Problem

Hi,

I used grid but I have a method as a class. I bind datasourse of grid like,

      DataSet dsCategories = null;
   dsCategories = ct.GetAllCategories();
   RadGrid2.DataSource = dsCategories;
Problem is paging in the grid. Becouse you suggested to us flowwing using.
   <asp:SqlDataSource ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
            ProviderName="System.Data.SqlClient" SelectCommand="SELECT CustomerID, CompanyName, ContactName, ContactTitle, Address, PostalCode FROM Customers"
            runat="server"></asp:SqlDataSource>

Instead of it, I want to use datasourse for paging or filtering etc.. How I bind it? Thanks.

Problem to editing dynamic grid

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.

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?
