[Solved] Getting values out of GridTemplateColumn Controls for Saving

[Pierre]

Hi there,

I am developing a Evaluation Control where Questions are listed and I need to get the following from the Grid to save as a 'Answer' to each of the Questions listed in the Grid:

~ The True/False Reply associated to a Question. [Basically which RadioButton is selected.]
~ Then also the Notes associated to a Question. [The Value from the TextBox.]

I am doing all my binding from the Code-behind. So I basically have to iterate through each bound row in the Grid and then persist the 'Answers' whan the Save Button is pressed.

Here is the Grid Markup:

<telerik:RadGrid ID="radgridList" runat="server" AllowSorting="False" AutoGenerateColumns="False"
        GridLines="none" OnNeedDataSource="radgridList_NeedDataSource">
        <MasterTableView Width="100%">
            <GroupByExpressions>
                <telerik:GridGroupByExpression>
                    <SelectFields>
                        <telerik:GridGroupByField FieldAlias="Catergory" FieldName="Title"></telerik:GridGroupByField>
                    </SelectFields>
                    <GroupByFields>
                        <telerik:GridGroupByField FieldName="Title" SortOrder="Descending"></telerik:GridGroupByField>
                    </GroupByFields>
                </telerik:GridGroupByExpression>
            </GroupByExpressions>
            <Columns>
                <telerik:GridBoundColumn HeaderText="QuestionId" DataField="QuestionId" UniqueName="QuestionId"
                    Visible="False">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn HeaderText="Body" DataField="Body" UniqueName="Body">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn HeaderText="Weighting" DataField="Weighting" UniqueName="Weighting">
                </telerik:GridBoundColumn>
                <telerik:GridTemplateColumn HeaderText="True" UniqueName="TrueSelection">
                    <ItemTemplate>
                        <asp:RadioButton ID="rbTrue" runat="server" GroupName="Selection" />
                    </ItemTemplate>
                </telerik:GridTemplateColumn>
                <telerik:GridTemplateColumn HeaderText="False" UniqueName="FalseSelection">
                    <ItemTemplate>
                        <asp:RadioButton ID="rbFalse" runat="server" GroupName="Selection" Checked="True" />
                    </ItemTemplate>
                </telerik:GridTemplateColumn>
                <telerik:GridTemplateColumn HeaderText="Notes" UniqueName="Notes">
                    <ItemTemplate>
                        <telerik:RadTextBox ID="txtNotes" runat="server" Width="250px">
                        </telerik:RadTextBox>
                    </ItemTemplate>
                </telerik:GridTemplateColumn>
            </Columns>
        </MasterTableView>
        <ClientSettings>
            <Selecting></Selecting>
            <Resizing AllowRowResize="True" AllowColumnResize="True" EnableRealTimeResize="True"
                ResizeGridOnColumnResize="False"></Resizing>
        </ClientSettings>
        <GroupingSettings ShowUnGroupButton="true" />
    </telerik:RadGrid>
    <div id="bottom" style="float:right; padding-top:10px;">
    <asp:Button ID="btnSave" Text="Save" runat="server" CausesValidation="True" onclick="btnSave_Click" /></div>

Any help as to how best to achieve the above functionality will be much appreciated.

Thanks!

Hello Pierre,

You can try out the following code to extract the template column data on clicking the save button:
c#:

protected void btnSave_Click(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.Items)
        {
            RadioButton rdbtn1 = (RadioButton)item.FindControl("rbTrue");
            RadioButton rdbtn2 = (RadioButton)item.FindControl("rbFalse");
            RadTextBox txtbx = (RadTextBox)item.FindControl("txtNotes");
            string strtxt1 = rdbtn1.Checked.ToString();
            string strtxt2 = rdbtn2.Checked.ToString();
            string strtxt3 = txtbx.Text;

            // update database

        }
    }

Thanks
Princy.
