Forms Data Controls :: DatagridView Postback / Cannot Make The Datagridview's Buttonfield Respond?

Feb 17, 2011

I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.

protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}

It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.

I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?

Forms Data Controls :: Return Number Of Rows In A Dataset?

Jan 14, 2010

I'm using a table adapter to perform my queries. I'm sure I'm missing something really easy, but I can't figure out how to return the number of rows returned from a query to a dataset used for a GridView.Basically, I want to display a message "No records exist for your selection" by testing for ReturnedRows = 0.

Excerpt of C# code:

handoutDSTableAdapters.handoutTableAdapter handoutsAdapter =
new handoutDSTableAdapters.handoutTableAdapter();
gv_Handout.DataSource = handoutsAdapter.GetDataByDoctor(Int32.Parse(ddl_MD.SelectedValue));
gv_Handout.DataBind();

Forms Data Controls :: Find Number Of Rows For Repeater Control?

Jan 19, 2010

I'm looking for the correct syntax to get me the last row of a repeater item and use it in a literal below. As you can see I have the item index syntax already. assume that there is a repeater control surrounding the literal already.

I have already bound the data so it will not use obitemdatabound .

<asp:Literal id="Rpt_ItemCount" runat="server"
Text = '<%# (int) DataBinder.Eval(Container, ItemIndex"))%>'></asp:Literal>

Forms Data Controls :: Creating A Form With An Unknown Number Of Rows?

Sep 13, 2010

I'm pretty new at ASP .NET but not to ASP. I've got a form I need to create where I don't know how many entries will be added. It has the following format:

"Age" "Duration" "Period of Duration" "etc..."

Last30Days

1-5 Months ago

6-11 Months ago

Age

Age

Age

etc.

So the Age column always has the first 3 options and then an unknown number of Age values that can be inserted. I've created a table that has the first four fields (Last30days, 1-5months, 6-11months, age) and I was thinking I could just order by those 4 columns for display. The problem I have is I'm not sure on how to proceed. Does anyone have any good ideas on how to handle this situation? Ideally data entry people could use the same form for both entering and displaying the data.

Forms Data Controls :: Listview - Fixed Number Of Rows In A Table?

Mar 29, 2010

I've searched for this several times but have never been able to find the answer with my search terms. Say you have a listview and a datapager set to 10 rows, but you only have 4 data items in the database at the time the query is run. Is there a way to force it to show a 10 row table (4 with data and 6 without)?

Everytime I search on this, I just find information on setting the number of rows for the datapager, which will not show empty rows if the data isn't there. Probably an easy solution, but the heck I can find it.

Forms Data Controls :: After Page Index Changed, Only Rows In First Page Are Accessible?

Jan 7, 2011

I have this function:

[Code]....

I set itemsRead and startRowIndex in ViewState:

[Code]....

This is my PageIndexChanged event:

[Code]....

My purpose is to modified some data only for current page in a gridview. I call this function in page load and GridView_PageIndexChanged events. When it's called in page load event, it works fine. But when it's called in PageIndexChanged event, only the rows on the first page in GridView are looped through. For example, if I click page 5, the rowStartIndex becomes 100 = 5 x 20 (my pagesize). The if condition becomes itemsRead >= 100 andAlso itemsRead < 120. But after itemsRead is increased to 19, the For each gridViewRow loop stops and the if condition is never satisfied.

Forms Data Controls :: Limit Number Of Selected Rows In Data Source For GridView?

Apr 30, 2010

I'm sure it was discussed hundred of times, but maybe this time will elucidate some new points )

The question is: do I need to limit number of selected rows in data source for GridView?

When I use paging in GridView does limiting selected rows make GridView work faster?

Now I use ObjectDataSource with Linq in functions.

[Code]....

Does this make sense or I can just use LinqDataSource without thinking of selected rows?

Forms Data Controls :: GridView Pager Not Showing Proper Number Of Rows?

Sep 9, 2010

I have created an out-of-the-box (default everything) ASP.NET Dynamic Data Entities Web Site using VS2010, C# and the .NET Framework 4. Created an ADO.NET Entity Data Model based off a MS SQL 2008 R2 database and registered that EF data model for my dynamic data. Everything works great except for the one change I would like to make. By default, the GridViewPager.ascx file provides the values 5, 10, 15 and 20 in the dropdown for GridView's "Results per page" option. I would like to change that to 10, 20, 30 and 40 - with 40 being the default selected option.

I went to the code behind file and modified it to have the values I am wanting. Those values now show in the dropdown, and work if I select them. Problem: when the page is first rendered only 10 rows will show. How can I change this?
