I Have a Table column Called Status which takes three Values 1, 2 or 3. Now, I want to Display another column Name1 in either of the three GridViews depending on the Status. Also I have link buttons which Redirect to different web forms.
This is the output I'm Getting. The ID of this GridView is GridView1
This is the code I've used

I have a page where I list all jobs. I have to program a button so that when I click on it, it directs me to that specific job details. How can I do that. I have tried navigateUrl but when I click on the button, nothing happens.
Here is my code for my item template

remove navigateUrl property from LinkButton and below one.
PostBackUrl="imagepage.aspx?v=<%#Eval("id") %>"
from query string you will get jobID. read JobId and display record.
Thanks, hope this will help you :)
Command Name does not work like this. Use below code for redirection
<asp:LinkButton ID="lnkmovdetails" runat="server" Text="View Details" PostBackUrl='~/jobdetails.aspx?id=<%#Eval("Job_ID") %>' CssClass="btn btn-info" />
I have a simple gridview with image button to update value of one of gridview column, by problem is whenever I click the image button it refresh the wholw page and I want the gridview only to be refreshed with updated value, I tried using UpdatePanel but it also refresh the whole page,
any help will be apprechiated.
aspx code:
<form id="form1" runat="server" >
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:GridView ID="GridView1" CssClass="datatable" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" AllowPaging="True" AllowSorting="True" PageSize="5">
<Columns >
<asp:BoundField DataField="req_id" HeaderText="request ID" SortExpression="req_id" />
<asp:BoundField DataField="req subject" HeaderText="request subject" SortExpression="req_subject" />
<asp:TemplateField>

<asp:ImageButton ID="Button_update" runat="server" CommandArgument='<%# Bind("req_id") %>' CssClass="yourCssClassIsNeedIt" ImageUrl="Images/under.png" OnClick="btn_under" UseSubmitBehavior="false" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
</form>
aspx.cs code:
protected void Button_update(object sender, ImageClickEventArgs e)
{
using (SqlConnection sqlCon = new SqlConnection(#"Data Source= DESKTOP-U9437PU; initial Catalog = Mydb; Integrated Security =True;"))
{
sqlCon.Open();
string sql = "update requests_table set stat_id = '2' where req_id ='" 5 "'";
SqlCommand cmd1 = new SqlCommand(sql, sqlCon);
cmd1.ExecuteNonQuery();
cmd1.Dispose();
sqlCon.Close();
}
GridView1.DataBind();
}
You need to set UpdateMode Conditional:
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button_update" EventName="Click" />
</Triggers>
<ContentTemplate>
<asp:GridView ID="GridView1" CssClass="datatable" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" AllowPaging="True" AllowSorting="True" PageSize="5">
<Columns >
<asp:BoundField DataField="req_id" HeaderText="request ID" SortExpression="req_id" />
<asp:BoundField DataField="req subject" HeaderText="request subject" SortExpression="req_subject" />
<asp:TemplateField>
<ItemTemplate>
<asp:ImageButton ID="Button_update" runat="server" CommandArgument='<%# Bind("req_id") %>' CssClass="yourCssClassIsNeedIt" ImageUrl="Images/under.png" OnClick="btn_under" UseSubmitBehavior="false" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
Then you should work call UpdatePanel1.Update(); as following:
protected void Button_update(object sender, ImageClickEventArgs e)
{
using (SqlConnection sqlCon = new SqlConnection(#"Data Source= DESKTOP-U9437PU; initial Catalog = Mydb; Integrated Security =True;"))
{
sqlCon.Open();
string sql = "update requests_table set stat_id = '2' where req_id ='" 5 "'";
SqlCommand cmd1 = new SqlCommand(sql, sqlCon);
cmd1.ExecuteNonQuery();
cmd1.Dispose();
sqlCon.Close();
}
GridView1.DataBind();
UpdatePanel1.Update();
}
Try this:
<asp:ImageButton ID="Button_update" runat="server" CommandArgument='<%# Bind("req_id") %>' CssClass="yourCssClassIsNeedIt" ImageUrl="Images/under.png" OnClick="btn_under" UseSubmitBehavior="false" OnClientClick="javascript:void(0);" />
And this
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true">

Here b_click should work but it is not working any help would be appreciated as I am new to this custom paging

my front end design
UI design
when I click that link it shows that following error message
An exception of type 'System.IO.DirectoryNotFoundException' occurred
in mscorlib.dll but was not handled in user code
Additional information: Could not find a part of the path 'F:\Visual

Uploading file is working perfectly, But I am not getting a download.
You don't supply a commandArgument for your RowCommand event. Change
<asp:LinkButton ID="LinkButton1" runat="server" CommandName="Download" Text='<%# Eval("File") %>'></asp:LinkButton>
to
<asp:LinkButton ID="LinkButton1" runat="server" CommandName="Download" CommandArgument='<%# Eval("File") %>' Text='<%# Eval("File") %>'></asp:LinkButton>
The only reason your code could fail would be if e.CommandArgument doesn't have a valid file name. I think the Command Argument isn't being passed for some reason, please look into your markup.
You have to explicitly specify CommandArgument for a LinkButton like this:
CommandArgument='<%# Eval("File") %>'
I have a gridview that I need a footer row inserted with the data from a textbox when the user hits submit. I have tried over and over and I can not get past the following error:
Object reference not set to an instance of an object. The error is flagged on the Textbox AddName line of code in the code behind.

It looks like your SqlDataSource2 is causing the error. Please double check that both Name and Email are of DB type string in your DB.
In your ASPX SqlDataSource2 make the following changes:
<InsertParameters>
<asp:QueryStringParameter Name="Name" QueryStringField="Name" DbType=String />
<asp:QueryStringParameter Name="Email" QueryStringField="Email" DbType=String />
</InsertParameters>
In your C# Code-Behind, change to this:
SqlDataSource2.InsertParameters[0].DefaultValue = txtAddName.Text;
