[Solved] Hide radtextbox with checkbox inside EditFormTemplate of radgrid

[Carina]

Is it possible to have a checkbox inside the editform template of a radgrid that will make a radtextbox visible when checked, and not visible when unchecked? All these controls would be in the EditFormTemplate of the radgrid and should be able to appear it and disappear it while still in EditForm. I am working with VB and I have looked at the examples, but none explain about checkbox, since they are different than radcomboboxes or dropdownlists.

Hello,

Please try with below code snippet.

Client side:

function ValidateGrid(obj) {
               var txt = $telerik.findTextBox(obj.id.replace("CheckBox1", "RadTextBox1"));
               txt.set_visible(obj.checked)
           }

<EditFormSettings EditFormType="Template">
                   <FormTemplate>
                       <asp:CheckBox ID="CheckBox1" runat="server" onclick="ValidateGrid(this);" />
                       <telerik:RadTextBox ID="RadTextBox1" runat="server">
                       </telerik:RadTextBox>
                   </FormTemplate>
               </EditFormSettings>

Server side:

<EditFormSettings EditFormType="Template">
                   <FormTemplate>
                       <asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="true" OnCheckedChanged="CheckBox1_CheckedChanged" />
                       <telerik:RadTextBox ID="RadTextBox1" runat="server">
                       </telerik:RadTextBox>
                   </FormTemplate>
               </EditFormSettings>

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
        {

            CheckBox CheckBox1 = sender as CheckBox;
            GridEditFormItem item = CheckBox1.NamingContainer as GridEditFormItem;
            RadTextBox RadTextBox1 = item.FindControl("RadTextBox1") as RadTextBox;
            RadTextBox1.Visible = CheckBox1.Checked;
        }

Hi,

I am trying to do it on the server side. I cannot do it that way because, I cannot access the check box because it is inside the radgrid. I am working in vb.net. I have tried many function in the Item databound of the radgrid, but nothing seems to work. Any ideas?

Hi,

You can attach checkchanged event for the checkbox as shown below.
VB:

Protected Sub CheckBox1_CheckedChanged(sender As Object, e As EventArgs)
Dim CheckBox1 As CheckBox = TryCast(sender, CheckBox)
    Dim item As GridEditFormItem = TryCast(CheckBox1.NamingContainer, GridEditFormItem)
    Dim RadTextBox1 As RadTextBox = TryCast(item.FindControl("RadTextBox1"), RadTextBox)
    RadTextBox1.Visible = CheckBox1.Checked
End Sub

Thanks,
Shinu
