Web Forms :: Why Gridview Isn't Working In DesignView
Mar 28, 2011
when i try to drag my database over from "database explorer" in the content surface . I then create a database.
app_data > add > new item >sql server compact > I then create my database , with the unique id field , followed by the required fields.
I then go database > tables > "testtable" and fill it in with information.
Now when i try to drag the database folder across to the content surface , gridview seems to be not working. Has this feature been removed ? And why does the database save in .SDF rather then .MDF , like the webform tutorial?

I have a gridview for which i have provided two options one to export grid data and another to import excel data to gridview. I have no problems with the former. In the latter part i want to achieve something like this. When user user exports gridview data to excel and lets say makes some changes i.e there were 10 items he deletes 4 of them. and saves the excel file.Now when he tries to import this excel file i want the checkbox(already present) to be checked for the 6 items of the 10 items in the gridview. how can i accomplish this. To import excel data to gridview i am using this method: In the importtogrid button,

I started to work with this control and I find it better to code it my self instead of using the wizard option that comes as a standard. Can I pass the values directly to the Query in my SqlDataSource when I update a row? Let me show you the code:
<asp:SqlDataSource ID="SqlDataSource" Runat="server" SelectCommand="SELECT [catCodigo], [catDescripcion], [catSite] FROM [Categories]"

I have a Gridview where I am presenting the data from a backend SQL DB. The values are populated into the Gridview without any problem and I am also able to Delete the rows and Update the info using the built in "Edit" Button, But when I try to insert some new value in a blank space nothing happens when I click on "Update" button. It just refreshes the page without any changes made. Below is my code for InsertCommand and also for DeleteCommand and UpdateCommand (which are working fine). There is also a column for "Record ID" which is the primary key in the table and is used in the Delete and Update command which is what I think is making these command work while it is not used (I don't know how to include it) in the Insert command.

I'm a newbie to .NET, so the solution might be really trivial. I have a database, I have an Entity Data Model, I add in my Index.aspx page an EntitryDataSource and a GridView. I connect them and everything works fine (the data is displayed as expected). The problem is that clicking on the coulmn name or on the pagination lists doesnt do a thing... Although I did set the properties AllowSorting="True" and AllowPaging="True". I also tried with another datasource type (SqlDataSource) and the same problem.

I have gridview with check box in every row. I also have a button which is not a part of gridview.
My target is to do something on the button click event for the checked rows.
My code is below;
[Code]....
and my code behind is:
[Code]....
But my problem is, if I click the check box, My code shows "cb.checked=false".
So I never go inside the "IF(cb!=null && cb.checked)".

Question for Print functionality in ASP.Net GridView control artical. I tried you code in my project, when click print current page, nothing happens.
So I download your code into my test web project "WebSite1", greate, it works.
Then in your CS.aspx page,
I added (which is the case of my project of using AJAX).
<asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate>
<div> <asp:GridView ID="GridView1" runat="server"
.......................... gridview stuff gose here .........................
</div> etc etc to close all the tags.
Now run, click print button nothing happens, no any error.
Can you see why put updatePanle for AJAX causing problem ?
I also have to pur EnableEventValidation="false" at top of the page to avoid

I am working on object data source and datagridview. I have given object data source to the grid view as the data source of grid. The issue which i m facing is that whenever i click on next page(like 2 or 3 or 1) it takes lot of time to fire. although it is fired but I have to wait a minute or two and then it fired.
Whenever I click any event(e.g. next page , page 5 ,3 or edit etc) of gridview it does not give response. If I wait for a minute then click one of event then it performs, and then again I have to wait to fire other event.

I can't seem to get either EmptyDataTemplate or EmptyDataText of a GridView to work. I'm fetching the GridView contents in de codebehind and attaching them with using DataBind(). I've tried having them as null and as an empty List, and in both cases the text I put intoEmptyDataTemplate or EmptyDataText is not displayed. What am I doing wrong?
EDIT (Code snippet) This is my GridView:
<asp:GridView ID="grid" runat="server" EmptyDataText="EMPTY"></asp:GridView>
And I've tried these two for binding the data:
grid.DataSource = new List<object>();grid.DataBind();grid.DataSource = null;grid.DataBind();

On Page1 of a project, I have a Gridview showing a table of customer names (showing CustID, CustName, CustJoinDate). When I click on a record, I have passed a querystring to Page2 showing an address table for that customer. This part works for me.
The SQL statement in simply: Select * from CustAddress where CustID = @cust
What I would like to do though, is capture that @cust to a session variable so that I can use it later on.

Why is the auto paging not working for me? Is that because it only works for BoundField? Mine is mostly
templatefield. Other than auto paging, everything else works fine. I have at least 20 rows, so once I
specify AllowPaging="ture" and PageSize="5", it should give 5 rows a page for 4-5 pages, right?
