[Solved] Getting the items from template

[Jebamalai]

Dear All,

I am new to Telerik grid.

I have created a custom template for editing the items.

When I clicked on the "Update" button the Item_Updated event is not triggered.

I referred the sample given in the live demos.

I am unable to get the items in the edit template, it is giving the old values not the edited values,  how can I get the edited values?

I also referred the below link:

Thanks a lot in advance.

Best Regards,
M. J. Jaya Chitra.

Hi Jaya,

You can get the edited or updated values in the UpdateCommand event as shown in the code snippet below.

ASPX:

<EditFormSettings>
            <FormTemplate>
                <asp:TextBox ID="TextBox1" Text='<%#Eval("ToandFro") %>' runat="server"></asp:TextBox>
                <asp:TextBox ID="TextBox2" Text='<%#Eval("FirstName") %>' runat="server"></asp:TextBox>
                <asp:LinkButton ID="LinkButton1" Text="Update" CommandName="Update" runat="server"></asp:LinkButton>
                <asp:LinkButton ID="LinkButton2" Text="Cancel" CommandName="Cancel" runat="server"></asp:LinkButton>
            </FormTemplate>
</EditFormSettings>

CS:

 protected void RadGrid1_UpdateCommand(object source, GridCommandEventArgs e)
    {
        if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
        {
            GridEditFormItem item = (GridEditFormItem)e.Item;
            TextBox txt = (TextBox)item.FindControl("TextBox2");
            string strtxt = txt.Text.ToString();
        }
    }

Thanks
Princy.

Hi Jaya,

You can also go through the following help articles.

Dear Shinu / Princy,

In my edit template I have bounded a dropdown list as follows:

<asp:DropDownList ID="ddlCountry" runat="server" DataTextField="CountryName" DataValueField="CountryCode"

DataSourceID="CountryList" SelectedValue='<%# Bind("CountryCode")%>'>

<asp:ListItem Text="Select" Value="" Selected="True"></asp:ListItem>

</asp:DropDownList>

When I am clicking on "Edit" it is working fine but while clicking on "Add" it is giving the following error:
"ddlCountry has a SelectedValue which is invalid becuase it does not exist in the list of items.  Parameter name: value".

Hi Jaya,

The reason for this error is that your grid instance can not bind a value for the newly inserted item through the Eval()/Bind() syntax you hard-coded (as you may have seen from the stack trace of the error).
 Go through the following help article which explains how to fix this problem.

Dear Princy,

Thank you for your reply.

It is useful, but I have fixed the issue as follows:

<asp:DropDownList ID="ddlCountry" runat="server" DataTextField="CountryName" DataValueField="CountryCode"   DataSourceID="CountryList" SelectedValue='<%# (Container is GridEditFormInsertItem) ? 1 : Eval("CountryCode") %>'>
</asp:DropDownList>

If this is wrong, kindly let me know the same.

Dear Princy / Shinu,

I have an issue while inserting the records.

In the Item_Command event I am checking whether the command name is a "RadGrid.UpdateCommandName", then I am updating and clearing the editindexes by using:
RadGrid1.EditIndexes.Clear();
The edit item is cleared and it is not displayed.

But while insetting the record, the edit index is zero and it is not clearing the edit template and it is still there after inserting also.

Can you help in this regard?


Thanks a lot in advance.

Hi Jaya,

Try the following line of code to close the Insert form after performing the  insert operation.

CS:

protected void RadGrid1_InsertCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
    {
        //code for insert
        //.....
        // Close the Insert form
        RadGrid1.MasterTableView.IsItemInserted = false;
    }

Thanks
Princy.

Dear Princy,

Based on your suggestion I have tried it, it is giving the error "Insert item is available only when the grid is in insert mode.

Do I need to write any code to make this?

[Shinu]

Hi Jaya Chitra,

Have you set AllowAutomaticInserts to true? Try setting it to false in the aspx as shown below.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server"  AllowAutomaticInserts="false" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" >

Thanks
Shinu
