Hi,

Are you trying to display and bind RadComboBox in grid column when the grid is in read mode (not edit mode)?

If yes, you can use GridTemplateColumn with RadComboBox in its ItemTemplate. With GridDropDownColumn, the drop down control is only available in edit/insert mode.

Check out this link for more info.

Basically I have four dropdowncontrol in RadGrid1. datasource for activity type and budget defined in design time but for product and activity date datasource is defined in server side. when i insert a new item product and activity date does not show up in the grid.
I thought i need to have coding in RadGrid1_ItemDataBound and RadGrid1_ItemCreated for that. Is my understanding right?. Could you give me any sample example. On insert mode and Edit mode actividate and product binds to grid control but once you updated or inserted , the activitydate and product does not show up/bind to RadGrid1.

67     protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)     
68     {     
69     
70         if (e.Item is GridDataItem && e.Item.IsInEditMode)     
71         {     
72             GridDropDownListColumnEditor list = (e.Item as GridEditableItem).EditManager.GetColumnEditor("ActivityTypeID") as GridDropDownListColumnEditor;     
73     
74     
75     
76     
77         }     
 



protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)     
132     {     
133         if (e.Item is GridDataItem && !e.Item.IsInEditMode)     
134         {     
135     
136             GridDropDownListColumnEditor dateColumnEditor = ((GridEditableItem)e.Item).EditManager.GetColumnEditor("DateID") as GridDropDownListColumnEditor;     
137     
138             RadComboBox activitiess = dateColumnEditor.ComboBoxControl;     
139     
140     
141             if (DataBinder.Eval(e.Item.DataItem, "activitydate").ToString() != string.Empty)     
142             {     
143                 string sss = Convert.ToDateTime(DataBinder.Eval(e.Item.DataItem, "activitydate")).ToShortDateString();     
144

157     
158             string ss = DataBinder.Eval(e.Item.DataItem, "activity_id").ToString();     
159     
160             int? activityId = null;     
161             if (ss != string.Empty)     
162             {     
163                 activityId = (int)DataBinder.Eval(e.Item.DataItem, "activity_id");     
164                     
165             }     
166

Hello Ami,

Can you confirm that your database is updated properly after insert/update?
Additionally, I suggest that you review this help topic on how to configure/customize GridDropDownColumn and verify you have set up you columns right.

Let me know how it goes.

Kind regards,

Hi Lana,

yes, the value of activitydate and product_id is being written in database table during insert and update mode.In database datatype for activitydate is set as Nvarchar(500) and product_id as int. The problem i'm having here is activity date and product does not bind to grid control right after insert or update a grid item.

So you are saying i don't need any code in the RadGrid1_ItemCreated  event handler for the condition of 

 

protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)

 

{

 

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

 

{

 

GridDropDownListColumnEditor list = (e.Item as GridEditableItem).EditManager.GetColumnEditor("ActivityTypeID") as GridDropDownListColumnEditor;

 

 

 

}

and
RadGrid1_ItemDataBound eventhandler for the condition of

 

 

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

 

{

 

if (e.Item is GridDataItem && !e.Item.IsInEditMode)

 

{

 

GridDropDownListColumnEditor dateColumnEditor = ((GridEditableItem)e.Item).EditManager.GetColumnEditor("DateID") as GridDropDownListColumnEditor;

 

 

RadComboBox activitiess = dateColumnEditor.ComboBoxControl;

 

 

}

Please let me know.Thanks

Hello Ami,

You might handle the ItemCreated and/or ItemDataBound events in case you need to perform additional configurations and customizations there. Otherwise you are not obliged to.

Can you verify that you have set the ListTextField, ListValueField, DataField and DataSourceID/DataMember properties of the problematic GridDropDownColumns as explained here?

All the best,
Iana

You are right i did not have those property set in design time as datasource for activitydate griddropdowncolumn i have defined in code behind.I have DataField only set in design time and other property i have defined in code behind.

This is what i'm doing in the Grid1_ItemDataBound Eventhandler

 

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

 

{

 

 

 

 

if (e.Item is GridDataItem && !e.Item.IsInEditMode)

 

{

 

 

 

 

GridDropDownListColumnEditor dateColumnEditor = ((GridEditableItem)e.Item).EditManager.GetColumnEditor("DateID") as GridDropDownListColumnEditor;

 

 

 

 

 

DropDownList ddActivity = dateColumnEditor.DropDownListControl;

 

 

 

 

 

foreach (GridDataItem GridItem in RadGrid1.Items)

 

{

ddActivity.DataSource = BindActivityDate(GridItem.OwnerTableView.DataKeyValues[GridItem.ItemIndex][

 

 

 

"key"]);

 

ddActivity.DataTextField =

 

 

 

"activitydate";

 

ddActivity.DataValueField =

 

 

 

"activitydate";

 

ddActivity.DataBind();

 

}

But still not showing.Thanks

Hi Ami,

Please try setting the ListTextField and ListValueField properties of the GridDropDownColumn in the apsx file, directly in the column declaration. Then you can use the following code in order to change the GridDropDownColumn datas source:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)  
{  
    if (e.Item is GridDataItem)  
    {  
        GridDataItem item = e.Item as GridDataItem;  
        GridDropDownListColumnEditor editor = item.EditManager.GetColumnEditor("DateID") as GridDropDownListColumnEditor;  
        editor.DataSource = BindActivityDate(GridItem.OwnerTableView.DataKeyValues[GridItem.ItemIndex]["key"]);  
    }  
} 

I hope this helps.
