RadGrid Dynamic columns and ItemDataBound

Can you statically define a column in a radgrid, dynamically add another column, and then manipulate either column in the grid's ItemDataBound event?

First I statically defined a RadGrid such as the following:

<telerik:RadGrid ID="grdResults" Height="100%" runat="server" OnNeedDataSource="grdResults_NeedDataSource" OnItemDataBound="grdResults_ItemDataBound" GridLines="None" AllowSorting="true" AllowPaging="false" AutoGenerateColumns="false">

<ClientSettings>

<Scrolling AllowScroll="true" UseStaticHeaders="true" SaveScrollPosition="false" />

<Selecting AllowRowSelect="true" />

</ClientSettings>

<MasterTableView>

<Columns>

<telerik:GridBoundColumn HeaderText="StatusCodeDescription" UniqueName="StatusCodeDescription" DataField="StatusCodeDescription" HeaderStyle-Width="8%"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>





then dynamically add a column in the page load like:




if (!Page.IsPostBack)
{
    var boundColumn = new GridBoundColumn();
    e.GridColumns.Add(boundColumn);
 
    boundColumn.HeaderText = "Select";
    boundColumn.DataField = "Id";
    boundColumn.UniqueName = "selectId";
}



and still use the ItemDataBound event to manipulate the dynamically added column?  

I can retrieve and manipulate the statically defined column, but I am unable to do the same for the 

dynamically added column?  



What am I doing wrong?

private void GridItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

var item = (GridDataItem)e.Item;

item["selectId"].Text = "test";

if (item["StatusCodeDescription"].Text.Length > 5)

item["StatusCodeDescription"].Text = item["StatusCodeDescription"].Text.Substring(0, 2) + "...";

}

Hide/Unhide columns

Hi,

As mentioned in a previous thread, am using the solution in this thread to hide/ unhide columns.

In my scenario, out of the 10 columns in the grid am displaying 6 when am first loading the page. Am using checkboxes to hide/unhide each column.

Am facing a problem displaying the columns that are hidden on pageload. Am able to hide/unhide the 6 columns that are displayed on page load. Am guessing this might be due to the viewstate too.

Any suggestions to fix this would be helpful.

Thank you.

GridHTMLEditorColumnEditor width

When I set the width of a RadEditor in a RadGrid, the content area is wider than the Editor (I mean I have an horizontal scrollbar). How could I avoid that?

My code to set the Editor's width is:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

{

GridEditableItem editedItem = e.Item as GridEditableItem;

GridHTMLEditorColumnEditor editor = (GridHTMLEditorColumnEditor) editedItem.EditManager.GetColumnEditor(colName);

editor.Editor.Width = Unit.Pixel(750);

[...]

Additional Form on Update

I have a RadGrid that is used to update items to a different status. A user is given a list of status's in a drop down and the can choose what status to change the item to. I'm not sure the best way to go about this, but I would like to popup a modal window or some type of form where the user has to fill in more information if they try to update an item with a certain status. Basically if a user selects a certain status and tries to update the row they would be prompted to fill out more information. Any suggestions on the best way to go about this would be appreciated.

exporting the radGrid to Excel and word

Hello All,

I have a grid. I have several small grids inside the grid. I want to export the grid to MS word using RadGrid1.MasterTableView.ExportToWord();
This works fine, but when I do RadGrid1.ExportSettings.IgnorePaging = true; then the small grids inside the bigger grid starts throwing error. I get the error message that small grid is null. I am doing the find of the small grid in
RadGrid1_ItemDataBound. below is my code

protected void RadGrid1_itemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

RadGrid RadGrid_DetailsHeader = (RadGrid)e.Item.FindControl("RadGrid_DetailsHeader");

RadGrid_DetailsHeaderBind(casRepHeader, RadGrid_DetailsHeader);

}

In the above code RadGrid_detailsHeader is my small grid inside RadGrid1. when I write the ignorePaging command, this radGrid_detailsHeader becomes null. I am not sure what am I doing wrong. I need to print this grid with paging. I have five grids inside the big grid.

I spend my whole day trying to work this out, but without success. I am willing to use Telerik reporting option or any other way is also fine.

I have to export this grid to MS word and Excel.

I really really need help with this one.

Any help or tips will be greatly appreciated.
