How to use both RadioButton and Checkbox in a RadTreeView

Hi,

I need to use a radio button just beside the rendered checkbox in a radtreeview.

I show a list of products in the treeview so that the users can select multiple products and make a set, but at the same time user needs to select a single product as the most favourite product. Using radio button in the treeview to identify the favourite product is a client requirement.

Could you please help me out of it. I dont even know whether the requirement has got a feasible solution. Help !!!!

Slow Filtering with RadGrid

I have a RadGrid and I’m experiencing very slow searching in the filtering. If I do a query on the server itself with a “select * from table where column LIKE ‘%blah%’ it can return the query in about a second. With the filtering it can take up to 20 seconds.

Is there a way to speed that up?

Select column dissapears in radGrid

I want to selectively disable checkboxes based on expression.

I add code to grid prerender to iterate through each GridDataItem and if condition met, I want to disable checkboxes for select column.

my aspx part:

<Columns>

<telerik:GridClientSelectColumn UniqueName="checkboxColumn">

</telerik:GridClientSelectColumn>

my code behind

foreach (GridDataItem item in radGrid.MasterTableView.Items)

{

if (item is GridDataItem)

{

for (int i = 1; i < renderedColumns; i++)

{

GridColumn column = radGrid.MasterTableView.RenderColumns[i];

Control control = item[column.UniqueName].Controls[0];

if (condition==true&&column.uniqueName=="checkboxColumn")

{

(control as CheckBox).Enabled=false;

}

As soon as this code run, the one that had met conditions dissapear from the page, not just getting disabled.
If I change like: (control as CheckBox).Enabled=false; to say: (control as CheckBox).Tooltip="test"; checkboxes also dissapear.

Telerik Radgrid How to retrieve textbox values from dynamically generated RadGrid columns?

I am dynamically creating a RadGrid and adding GridTemplateColumns to it. Those columns have textbox in them.
After binding datatable to the grid, after user makes changes to the textboxes and on clicking save button, I would like to access the textbox values. But I am stuck at getting hold of the textbox instance. I couldn't even get hold of GridItems!
To add more complexity, my RadGrid is in a UserControl, which is in a (multi)view.
Since my control is in view, it's Page_Init is called more than once for each action that involves this view.

Once the gridstructure is defined, it has no need to change, but I think I should be calling it on Page Init or Load every time..

I have column paging instead of row paging, so there is custom code to handle that.
I would like to get some advice on the best place to call NeedDataSource, DefineGridStructure and where to get Postback values.
I have read this article, but it has sparse information for my need. http://www.telerik.com/help/aspnet-ajax/grid-programmatic-creation.html
Heres my code.

protected void Page_Init(object sender, EventArgs e)

{

DefineGridStructure();

}

      protected void Page_Load(object sender, EventArgs e)
      {
          if (RadGrid1 != null && RadGrid1.Items.Count > 0)
          {
              string strtxt = ((TextBox)RadGrid1.Items[1]["ProductGroup1"].Controls[0]).Text;//For starters, load one control and check it's state
          }
      }

private void DefineGridStructure()

{

RadGrid1 = new RadGrid();

RadGrid1.AutoGenerateColumns = false;

RadGrid1.ShowHeader = true;

RadGrid1.NeedDataSource += RadGrid1_NeedDataSource;

foreach(GridColumn qtyColumn in BuildGridQtyColumns(PaxColumnCount))

{

RadGrid1.MasterTableView.Columns.Add(qtyColumn);

}

//Add grid to page

phRadGrid.Controls.Add(RadGrid1);

}

private List<GridColumn> BuildGridQtyColumns(int count)

{

List<GridColumn> qtyColumns = new List<GridColumn>();

for (int i = 1; i <= count; i++)

{

string qtyColumnName = string.Format("ProductGroup{0}", i);

GridTemplateColumn qtyColumn = new GridTemplateColumn();

qtyColumn.ItemTemplate = new GridNumberTemplate(qtyColumnName);//Creates a textbox control

qtyColumn.UniqueName = qtyColumnName;

qtyColumn.HeaderText = "Qty";

qtyColumn.HeaderStyle.Width = Unit.Pixel(60);

qtyColumn.HeaderStyle.HorizontalAlign = HorizontalAlign.Center;

qtyColumns.Add(qtyColumn);

}

return qtyColumns;

}

Select all only selects items on first page

Within a RadGrid that uses the NeedDataSource method and using paging, there is a select all column. When the Header checkbox is selected, the items on the first page are selected only. How can I select all of the records within the RadGrid.

This is the code I have in place for selecting all dataitems:

CheckBox headerCheckBox = (sender as CheckBox);
foreach (GridDataItem dataItem in this.radgridmailinglists.MasterTableView.Items)
{
    (dataItem.FindControl("chxselectrow") as CheckBox).Checked = headerCheckBox.Checked;
    dataItem.Selected = headerCheckBox.Checked;
}
