How to fix this code for printing this GridView control?

How to fix this code for printing this GridView control? - c#

I am developing an intranet web application which works as a Suggestions Box. The Admin will see a list of all submitted suggestions in a GridView and he has the ability to accept or reject these suggestions.
Under this GridView, there is another GridView that shows the suggestions with their status as Accepted or Rejected. The admin wants to print this second GridView. I followed this Tutorial about printing any ASP.NET control and everything works well.
My ASP.NET Code:
<asp:Panel ID="Panel1" runat="server">
<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False"
AllowSorting="True" CssClass="mGrid"
AlternatingRowStyle-CssClass="alt"

<AlternatingRowStyle BackColor="White" ForeColor="#284775" />
<HeaderStyle Font-Bold = "true" ForeColor="Black" Height="20px"/>
<Columns>
<asp:BoundField DataField="SubmittedMonth" HeaderText="Submitted Month"

}
I was able to print this table but when I put it inside UpdatePanel control I can't print it and I don't know why. Any Idea? Any help?

I assume that when you say you "can't print", you mean that your javascript doesn't run. Try something like the following:
ScriptManager.RegisterStartupScript(Gridview2, Gridview2.GetType(), "onclick", "window.open('Print.aspx','PrintMe','height=400px,width=800px,scrollbars=1');", true);

ASP.NET Bulk Edit GridView Save button

I use this Bulk Edit GridView Control http://aspnetrealworldcontr.codeplex.com/
I use Linq and have a Stored Procedure to update the database.
I don't Understand how to use the Save Button to update the database.
You are suppose to update all the rows with one button.
In the example they use SqlDataSource
example
<div>
<asp:Button runat="server" ID="SaveButton" Text="Save Data" />
<rwg:BulkEditGridView ID="EditableGrid" DataSourceID="PubsDataSource" AutoGenerateColumns="False"
DataKeyNames="au_id" SaveButtonID="SaveButton" runat="server">
<Columns>
<asp:BoundField HeaderText="Last Name" DataField="au_lname" />
<asp:BoundField HeaderText="First Name" DataField="au_fname" />
<asp:BoundField HeaderText="Phone" DataField="phone" />
<asp:BoundField HeaderText="Address" DataField="address" />
<asp:BoundField HeaderText="City" DataField="city" />
<asp:BoundField HeaderText="State" DataField="state" />
<asp:BoundField HeaderText="Zip Code" DataField="zip" />
<asp:CheckBoxField HeaderText="Contract" DataField="contract" />
</Columns>
</rwg:BulkEditGridView>
<asp:SqlDataSource ID="PubsDataSource" runat="server"
SelectCommand="SELECT [au_id], [au_lname], [au_fname], [phone], [address], [city], [state], [zip], [contract] FROM [authors]"
UpdateCommand="UPDATE [authors] SET [au_lname] = #au_lname, [au_fname] = #au_fname, [phone] = #phone, [address] = #address, [city] = #city, [state] = #state, [zip] = #zip, [contract]=#contract WHERE [au_id] = #au_id"
ConnectionString="<%$ ConnectionStrings:Pubs %>" />
</div>
My Code - Only the Quantity can be updated.

Error when clicking edit in gridview

Error Message:
The variable name '#Bitnet' has already been declared. Variable names must be unique within a query batch or stored procedure. When trying to edit gridview.
I want to be able to update the checkbox field. This gridview is based on a table join.

</asp:SqlDataSource>

You have to declare the parameter first. Then only you can use that. It should be something like this
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ASPLOGINConnectionString %>" SelectCommand="SELECT IALO.INST_ID, IALO.FirstName, IALO.LastName, IALO.Prefix, IALO.Title, IALO.Address1, IALO.City, IALO.State, IALO.Zip, IALO.Country, IALO.Phone, IALO.Fax, IALO.BITNET, IALO.Active FROM CEOTable INNER JOIN IALO ON CEOTable.Inst_ID = IALO.INST_ID WHERE (CEOTable.Bitnet = #Bitnet)">
<SelectParameters>
<asp:Parameter Name="Bitnet" Type="Int32" DefaultValue="0" />
</SelectParameters>
<UpdateParameters>
<asp:Parameter Name="Bitnet" Type="Int32" DefaultValue="0" />
</UpdateParameters>
</asp:SqlDataSource>

I solved my own question issue was that I was not clearing my parameters first
protected void Page_Load(object sender, EventArgs e)
{
SqlDataSource1.SelectParameters.Clear();
}
That fixed the issue it works fine now.

Master Detail Gridview asp.net C#

I am trying to make something like this:
Master detail gridview
But give me error in this line from cs file when i click Show details in the GridView:
gvRow.FindControl("GridView2").Visible = true;
I am trying when i click Show details to see the Names from other table where ID_Proba is = to ID from first Table.

<SelectParameters>
<asp:Parameter Name="id_proba" Type="Int32" />

This is the cs file:
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
foreach (GridViewRow gvRow in GridView1.Rows)
{
gvRow.FindControl("GridView2").Visible = true;
}
SqlDataSource2.SelectParameters[0].DefaultValue = GridView1.SelectedDataKey[0].ToString();
GridView1.SelectedRow.FindControl("GridView2").Visible = true;
}

You need to take "GridView2" out of the EmptyDataTemplate and put it in a TemplateField. When you have data, the EmptyDataTemplate is not created at all, and also there is no grid in each row, because this template is for the whole grid.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"

How to get a refreshed table without refreshing the whole page?

I am developing an ASP.NET intranet web application which is a Quiz Engine. Since I am a new ASP.NET developer, I have a table that shows some feedback received from the users and the admin has the ability to accept or reject these feedback using the DropDownList.
Under this table, there is a JQuery Accordion that when the Admin clicks on it, he will see a table with the received feedback for the last three months. But when the admin accepts or rejects one of the feedback and then clicks on the Accordion, he will see the that table but without that feedback even if the feedback is one of the feedbacks submitted last month. However, when you refresh the page and then clicks on the Accordion, he will see it.
So is there any functionality that will help me to get an auto-refresh table with refreshing the whole page?
Any help please?

In the trigger you mentioned Click event, but in the code behind you have only DropDownList_SelectedIndexChanged event.
Instead you can trigger the SelectedIndexChanged event for the DropDownList as
<asp:AsyncPostBackTrigger ControlID="DropDownList" EventName="SelectedIndexChanged" />
You just need to trigger a valid event in the code behind.
Update: Since the SelectedIndexChanged updates the database, so you need to refresh the DataGrid to populate the updated data.
Add this line code at the end of SelectedIndexChanged method:
GridView2.DataBind();

How to let this DropDownList (filter) works again with this GridView?

I am developing an intranet web application which works as a Suggstions Box. The Admin will see a list of all submitted suggestions in a GridView and he has the ability to accept or reject these suggestions through the DropDownList that is added to the GridView. Besides that, there is a DropDownList at the top of this GridView to filter the suggestions based on the Division of the user who submitted one of these suggestions.
In addition, under this GridView, there is another GridView that shows the suggestions with their status as Accepted or Rejected. This GridView will be refreshed immediately after each time the admin accepts or rejects one of the suggestions. Also, the Admin has the ability to print this GridView.
Everything was working fine before adding the second GridView inside the UpdatePanel control, but now the filter for filtering the suggestions in the first GridView is not working. Any idea? Any help please?

Can you specify what is the id for the 1st grid?
What I can conceive is that maybe you are not updating the updatepanel manually on your selectedIndex change event
using (SqlConnection conn = new SqlConnection(connString))
{
using (SqlCommand cmd = new SqlCommand(updateCommand, conn))
{
cmd.Parameters.Clear();
cmd.Parameters.AddWithValue("#StatusID", suggestionStatus);
cmd.Parameters.AddWithValue("#ID", ID);
conn.Open();
cmd.ExecuteNonQuery();
}
conn.Close();
}
GridView2.DataBind();
UpdatePanel1.Update();
Also in your aspx set UpdateMode="Conditional"
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

How to fix this code for printing this GridView control? - c#

I assume that when you say you "can't print", you mean that your javascript doesn't run. Try something like the following: ScriptManager.RegisterStartupScript(Gridview2, Gridview2.GetType(), "onclick", "window.open('Print.aspx','PrintMe','height=400px,width=800px,scrollbars=1');", true);
