Error handling for radiobutoon with textbox in asp.net webform

I need to display error if user selects "Other" Radio button and leaves it blank or enters wrong data in textbox. once user enters right data error goes away.
<asp:RadioButtonList ID="radyears" AutoPostBack="true" runat="server" Height="63px" Width="100px" OnSelectedIndexChanged="radyears_SelectedIndexChanged" Font-Names="Arial" Font-Size="12pt">
<asp:ListItem Selected="True" Value="15">15 Years</asp:ListItem>
<asp:ListItem Value="30">30 Years</asp:ListItem>
<asp:ListItem>Other</asp:ListItem>
</asp:RadioButtonList>
<asp:TextBox ID="txtother" runat="server" AutoPostBack="True" Font-Names="Arial" Font-Size="12pt" Width="150px" MaxLength="10"></asp:TextBox>
<asp:Label ID="lblothererror" runat="server" Font-Names="Arial" Font-Size="11pt" ForeColor="Red"></asp:Label>
Below is image showing how radiobutton shows with textbox and error message label next to textbox.
Here is image of radiobutton display
##### Here is my Try
if (radyears.SelectedValue == "Other")
{
if (String.IsNullOrEmpty(txtother.Text) || (!double.TryParse(txtother.Text, out years)))
{
lblothererror.Text = "Not Valid Input";
return;
}
else
{
lblothererror.Text = "valid number";
return;
}

Try this code :-
<asp:RadioButtonList ID="radyears" AutoPostBack="true" runat="server" Height="63px" Width="100px" Font-Names="Arial" Font-Size="12pt" OnSelectedIndexChanged="radyears_SelectedIndexChanged">
<asp:ListItem Selected="True" Value="15">15 Years</asp:ListItem>
<asp:ListItem Value="30">30 Years</asp:ListItem>
<asp:ListItem>Other</asp:ListItem>
</asp:RadioButtonList>
<asp:TextBox ID="txtother" runat="server" AutoPostBack="True" Font-Names="Arial" Font-Size="12pt" Width="150px" MaxLength="10" OnTextChanged="txtother_TextChanged"></asp:TextBox>
<asp:Label ID="lblothererror" runat="server" Font-Names="Arial" Font-Size="11pt" ForeColor="Red"></asp:Label>
and in aspx.cs page
protected void radyears_SelectedIndexChanged(object sender, EventArgs e)
{
if (radyears.SelectedValue == "Other")
{
lblothererror.Text = "Enter age in Textbox";
}
else
{
lblothererror.Text = "";
}
}
protected void txtother_TextChanged(object sender, EventArgs e)
{
if (radyears.SelectedValue == "Other")
{
double years = 100;
if (String.IsNullOrEmpty(txtother.Text) || (Convert.ToInt32(txtother.Text) > years))
{
lblothererror.Text = "Invalid";
}
else
{
lblothererror.Text = "valid";
}
}
else
{
lblothererror.Text = "";
}
}

Try this
Here is c# code
protected void radyears_SelectedIndexChanged(object sender, EventArgs e)
{
if (radyears.SelectedValue == "Other")
{
lblothererror.Text = "Enter value in Textbox please";
}
}
protected void txtother_TextChanged(object sender, EventArgs e)
{
if (radyears.SelectedValue == "Other")
{
double years = 123;//Any Value
if (String.IsNullOrEmpty(txtother.Text) || (!double.TryParse(txtother.Text, out years)))
{
lblothererror.Text = "Not Valid Input";
return;
}
else
{
lblothererror.Text = "valid number";
return;
}
}
else
{
lblothererror.Text = "";
return;
}
}
and here it is
<asp:RadioButtonList ID="radyears" AutoPostBack="true" runat="server" Height="63px" Width="100px" OnSelectedIndexChanged="radyears_SelectedIndexChanged" Font-Names="Arial" Font-Size="12pt">
<asp:ListItem Selected="True" Value="15">15 Years</asp:ListItem>
<asp:ListItem Value="30">30 Years</asp:ListItem>
<asp:ListItem>Other</asp:ListItem>
</asp:RadioButtonList>
<asp:TextBox ID="txtother" runat="server" OnTextChanged="txtother_TextChanged" Font-Names="Arial" Font-Size="12pt" Width="150px" MaxLength="10"></asp:TextBox>
<asp:Label ID="lblothererror" runat="server" Font-Names="Arial" Font-Size="11pt" ForeColor="Red"></asp:Label>

Add new record to Telerik RadGrid

I have the following Telerik RadGrid, which I'm using in C#:
<MasterTableView Width="100%" EditMode= "InPlace" ClientDataKeyNames="menuID" CommandItemDisplay= "Top">
<Columns>
<telerik:GridBoundColumn DataField="Name" HeaderText="Name" SortExpression="Name" UniqueName="Name"></telerik:GridBoundColumn>
<telerik:GridTemplateColumn UniqueName="Type" HeaderText="Type">
<ItemTemplate>
<asp:TextBox ID="Type" Text='<%# DataBinder.Eval(Container.DataItem, "Type") %>' runat="server"></asp:TextBox>
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn UniqueName="List" HeaderText="List">
<ItemTemplate>
<asp:CheckBox ID="List" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "List") %>' />
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn UniqueName="loadAtStart" HeaderText="loadAtStart">
<ItemTemplate>
<asp:CheckBox ID="loadAtStart" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "loadAtStart") %>' />
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</telerik:GridTemplateColumn>
</Columns>
</MasterTableView>
The grid is populated with data, and working normally when editing the data.
But when I click on the Add New Record button provided by Telerik, then an empty row is added without any TextBox or CheckBox in the columns to edit in the new Row added. It's just an empty row. I presume that I have to create the controls dynamically in the called ItemDataBound event, but I didn't manage to find the actual code for this.
How do I solve this?

Please try with the below code snippet.

I have modified the parameters according to my requirement and also included all CURD operations.

Hope this would help you :-)

I'm not really a fan of any of these solutions because they require the use of Session. Session has it's place but I believe it's used more as a crutch.
You're already sending the RadGrid information back to the server-side via ViewState due to the PostBack so why not use it's information instead of relying on an in-memory store.
Example of Adding and Removing an item from a Grid. Yes, it does require iterating items to rebuild a List but it's an alternative to Session so I believe it has merit.
protected void addValueToRecentTagList(string text)
{
List<string> items = new List<string>();
foreach(GridDataItem row in RadGridNewTags.Items)
items.Add(row["tag"].Text);
items.Add(text);
RadGridNewTags.DataSource = items;
RadGridNewTags.DataBind();
}
protected void removeValueFromRecentTagList(string text)
{
List<string> items = new List<string>();
bool rebind = false;
foreach (GridDataItem row in RadGridNewTags.Items)
{
if (row["tag"].Text == text)
rebind = true;
else
items.Add(row["tag"].Text);
}
if (rebind)
{
RadGridNewTags.DataSource = items;
RadGridNewTags.DataBind();
}
}

You have to insert a control in the EditItemTemplate to display in Edit or Insert mode.
Or you can add an InsertItem Template and place a control in there:
<telerik:GridTemplateColumn UniqueName="loadAtStart" HeaderText="loadAtStart">
<ItemTemplate>
<asp:CheckBox ID="loadAtStart" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "loadAtStart") %>' />
</ItemTemplate>
<EditItemTemplate>
<asp:CheckBox ID="cbxEditLoadAtStart" runat="server" Checked='<%# Bind("loadAtStart") %>' />
</EditItemTemplate>
<InsertItemTemplate>
<asp:CheckBox ID="cbxInsertLoadAtStart" runat="server" />
</InsertItemTemplate>
</telerik:GridTemplateColumn>

model binding webform TryUpdateModel not Working

I have a simple formview and simple modelbinding in webform:
<asp:FormView ID="frm" ItemType="SabaDoor2.Models.Content" SelectMethod="frm_GetItem" UpdateMethod="frm_UpdateItem" DataKeyNames="Id" runat="server">

<asp:Label ID="lblDescription" Text='<%# Item.Description %>' runat="server"></asp:Label>
</p>
<p>
<asp:Button ID="btnEdit" Text="edit" CommandName="Edit" runat="server" />
</p>
</fieldset>
</ItemTemplate>
<EditItemTemplate>
<fieldset>
<legend>
<asp:Label ID="lblName" Text='<%# Item.Name %>' runat="server"></asp:Label>

<br />
</EditItemTemplate>
</asp:FormView>
and in code:

lblResult.ForeColor = System.Drawing.Color.Green;
lblResult.Text = "";

}
var result = TryUpdateModel(item);
if (ModelState.IsValid)
{
_db.SaveChanges();
}
}
public override void Dispose()
{
_db.Dispose();
base.Dispose();
}
tryUpdateModel return true but my model(description field) doesn't update
:(

I find out logical error:
i have to initialize BindItem.Name property instd of item.Name
Text='<%# BindItem.Description %>'

Spacing messed up

What is up with my spacing here? When the labels contain text the spacing is fine but then they are empty they have white space between each label. Why is extra space being added when the labels contain empty text?
With text in labels (what I want it to look like):
With no text in labels (how I do not want it to look like):
On the C# code behind side:
// On page load
for (int i = 1; i < 10; i++)
{
string ID = i.ToString();
PopulateLastNameLabel(ID);
}
protected void PopulateLastNameLabel(string ID)
{
Label lbl = new Label();
lbl.Width = 70;
lbl.Height = 20;
lbl.Text = "";
lbl.BackColor = System.Drawing.Color.Red;
lbl.ID = "lastname_" + ID;
pnlLastNameLabel.Controls.Add(lbl);
}
On the ASP.NET side:
<asp:Table ID="tblDisplayTable" runat="server">
<asp:TableRow>
<asp:TableCell>
<asp:Panel ID="pnlPrizeNumberLabel" runat="server" Width="80px"></asp:Panel>
</asp:TableCell>

</asp:TableCell>
</asp:TableRow>

If I understand you question correctly, you need the following css (remove height from code behind).
The problem each control is in own table cell, so they won't horizontal align properly. So you need to set height explicitly for each control.
<style type="text/css">
td div { margin-right: 5px; }
td div input {border: 1px solid #828282; height: 21px; }
td div span { height: 25px; line-height: 25px; }
</style>

lbl.Text = "";
lbl.BackColor = System.Drawing.Color.Blue;

}
I prefer creating controls one row at a time instead of one column at a time, but that is not OP.

trigger for a button in a gridview in update panel

I have a gridview in an update panel and it is working fine. However on the click of the edit button I want to open the edit form. But the edit button click is not working. When i debug it, the method is working fine however the page doesn't postback. I have tried using triggers but to no avail.
