[Solved] Add New Record not working

[maha]

I have the following Grid. When i click on the commanditem "Add New condition Group" in Master record or Add new condition to this group in Detail record, the entire row becomes empty.
Not sure what is causing this. Can someone help.


Thanks, in advance.

The following grid is within another grid as one of the column. In this grid i am setting datasource for the below grid.

Hello Maha,

Could you please let us know how you populate your RadGrid with data? The described behavior is observed when using simple data-binding. For more information please examine the following links:

Hi Maha,

If the entire Grid rows are getting empty on clicking the AddNewRecord button it may be due to Simple-Databinding as Telerik said. But If it is a single row that is getting empty I guess you might have misunderstood the Insert Form(InPlace) as an empty Grid row. If you dont want the Inplace editing you may set the EditMode to EditForms .

Regards
Shinu

It looks like the databinding issue. I added NeedDatasource and testing it.

[maha]

I added the needdatasource and i am now able to see everything fine.

I have two other issues though.

issue 1 : I have RadComboBox and i have a selectedindex changed event associated with that control.

When i change an item in the combobox i am getting an error  cannot convert GridForInsertedItem to GridDataItem.

Below is the code i have on SelectedIndexChanged event.

 

 

protected

 

void rcbParameter1_SelectedIndexChanged(object sender, EventArgs e)

 

{

 

RadComboBox rcbParameter1 = (RadComboBox)sender;

 

 

GridDataItem row = (GridDataItem)rcbParameter1.NamingContainer;

 

 

RadComboBox rcbParameterDP1 = (RadComboBox)row.FindControl("rcbParameterDP1");

 

 

parameterClassName = rcbParameter1.SelectedValue;

rcbParameterDP1.DataSource = RuleParameterDS.Select();

rcbParameterDP1.DataBind();

}

Issue 2:

 

 

Insert button and cancel button is not displayed after i click 'Add new Record'.
Whct could be the possible reason for that.

I would really appreciate your help.
Thanks in advance.

Hi Maha,

From the previous forum post I can see that you are using the same RadComboBox in the ItemTemplate as well as EditItemTemplate and in the code behind you are casting the NamingContainer of the RadComboBox as GridDataItem which will throw an error when you try to change the selection of the combobox in the Insert mode( where you need to cast the NamingContainer  as GridDataInsertItem/GridEditFormInsertItem).

//Here is the sample code in insert mode:
CS:

 protected void rcbParameter1_SelectedIndexChanged(object sender, EventArgs e)
    {
        RadComboBox rcbParameter1 = (RadComboBox)sender;

        if ((rgRuleConditionsGroup.MasterTableView.IsItemInserted)&&(rgRuleConditionsGroup.EditIndexes.Count==0))
        {
            GridDataInsertItem row = (GridDataInsertItem)rcbParameter1.NamingContainer;

            RadComboBox rcbParameterDP1 = (RadComboBox)row.FindControl("rcbParameterDP1");
            parameterClassName = rcbParameter1.SelectedValue;
            rcbParameterDP1.DataSource = RuleParameterDS.Select();
            rcbParameterDP1.DataBind();

        }


    }
