Hi,

I have a radgrid (inside the combobox) which is groupped with one of the columns and I want to have the groups also to be selectable when clicked. Is this possible somehow just like onrowselect?

Thanks & regards,
Pete

Hi Pete,

I guess you are trying to select/unselect the Grouped items on clicking the GridGroupHeaderItem. If so you can try the following code snippet to achieve the required scenario.

ASPX:
<input id="Hidden1" type="hidden"  runat="server" /> 

CS:
  protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e) 
    { 
        if (e.Item is GridGroupHeaderItem) 
        { 
            GridGroupHeaderItem item = (GridGroupHeaderItem)e.Item; 
            string GroupIndx = item.GroupIndex; 
            item.Attributes.Add("onClick""SelectGroup('" + GroupIndx + "');"); 
        } 
   } 

 protected void RadGrid1_PreRender(object sender, EventArgs e) 
    { 
        if (Hidden1.Value!=string.Empty) 
        { 
            foreach (GridGroupHeaderItem groupHeader in RadGrid1.MasterTableView.GetItems(GridItemType.GroupHeader)) 
            { 
                if (groupHeader.GroupIndex == Hidden1.Value) 
                { 
                    GridItem[] children = groupHeader.GetChildItems(); 
                    foreach (GridItem child in children) 
                    { 
                        child.Selected = !child.Selected; 
 
                    } 
                } 
            } 
        } 
   } 

JS:
<script type="text/javascript"
 
function SelectGroup(GroupIndx) 
var input=document.getElementById('Hidden1'); 
input.value=GroupIndx; 
__doPostBack('RadGrid1.ClientID'
 
</script>

Hi,

No, I want to select a group row itself so that it is possible to select either data row or group row from the grid.

Regards,
Pete

Hi Pete,

On suggestion will be to apply backcolor for the GridGroupHeader while clicking on it. Give a try with following code snippet and see if it helps.

CS:
 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e) 
    { 
 
        if (e.Item is GridGroupHeaderItem) 
        { 
            GridGroupHeaderItem item = (GridGroupHeaderItem)e.Item; 
            item.Attributes.Add("onClick""if(this.style.backgroundColor!='red'){this.style.backgroundColor='Red';}else{this.style.backgroundColor='Transparent';}"); 
        } 
    }

Hi,

I think that I didn't explain clear enough what I try to do.

So I have RadGrid placed inside the RadComboBox and when the user selects a data row from the grid then the selected grid row's text/value is set as combobox selected text/value using the following code.

function onRowSelected(sender, args)   
{  
    var selectedText = args.getDataKeyValue("TypeName");  
    var selectedValue = args.getDataKeyValue("ID");  
 
    // get combobox  
    var combo = $find("ctl00_cph_rcbTest");  
 
    if (selectedValue.length > 0)   
    {  
        combo.trackChanges();  
        combo.set_text(selectedText);  
        combo.get_items().getItem(0).set_text = selectedText;  
        combo.get_items().getItem(0).set_value(selectedValue);  
        combo.commitChanges();  
        combo.hideDropDown();  
    }  

Now I want to do this same when user clicks the group row.

Regards,
Pete
