select value from combox and set into other text box

[Vinh]

Hi,

I have a RadGrid with 2 column (customer_number, and customer_name). When I click on the Add New Record, I would like to build 2 combox (google like), 1 for customer_number and 1 for customer_name, both has 2 columns customer_number and customer_name and  when we select a value from either box, I would like to update the other box with its corresponding value.  These comboxes are pulling data from MS Access while this RadGrid is from SQL.

Thanks

Hello,


One suggestion is using GridTemplateColumns with RadComboBoxes in EditItemTemplate and then attach the OnSelectedIndexChanged event to comboboxes. Now in the OnSelectedIndexChanged event, get reference to other combo and set the SelectedValue accordingly.

I hope you will get hint on performing this by going through the following forum:
Load on demand with two comboboxes in grid

CS

protected void RadComboBox1_OnSelectedIndexChanged(object sender, EventArgs e)
{
    RadComboBox radCombo1 = (RadComboBox)sender;
    GridEditFormItem editItem = (GridEditFormItem)radCombo1.NamingContainer;
    TextBox txtCustomerNumb = (TextBox)editItem.FindControl("txtCustomerNumb");
    TextBox txtCustomerName = (TextBox)editItem.FindControl("txtCustomerName");
    .......
}

Thanks again

Hello Vinh,

Judging by the provided information, you are trying to wire a server event handler to a client side event. Please check whether the event name is spelled correctly - OnSelectedIndexChanged or OnClientSelectedIndexChanged.
