I'm using a GridView and DataGrid. To use some JQuery I'm trying to get to work it needs to render the THeader and TBody. How do I force the DataGrid and GridView to render these elements?
View 1 RepliesI have a curious issue,I am using a combination of asp.net controls with Jquery and am using the JQuery plug called datatables. Instead of applying this to a html table, I applied it to an asp.net gridview. To get it to work, I had to add the thead and tbody tags to the grid like so in the c#:
tablename.UseAccessibleHeader = true;tablename.HeaderRow.TableSection = TableRowSection.TableHeader;
The issue is, is when data is filtered in the table, often there are no results and the emptydatatemplate is used. When this occurs the thead and tbody tags are not in the source outputted by the browser, and an occur occurs and the jquery does not function. Error: 'asSorting' is null or not an objectDoes anyone know a solution? I need to use both the gridview and the jquery datatables ideally.
I have a datagrid with columns programatically populated. I need access to the columns to modify the sort expression prior to render, but the column count is 0 at every stage I try to access them. Break points are hit, but each check of the count = 0.Have tried the following, accessing in various stages of the page / control life cycle, but in all instances, the column count is 0.
protected void Page_PreRenderComplete( object sender, EventArgs e )
{
if (dgPriceInfo != null)

Using ASP.NET Web Forms.I am databinding a DataView to a DataGrid with AutoGenerateColumns set to trueThe final column of the DataView is not rendering.Using the debugger I can see that the column definitely exists in the data grid's datasource. The column is of type decimal and some of the rows in the column have data in them.The column has a column name.The other columns are rendering fine.What's going on?Some more infoFunnily enough, I can set AutoGenerateColumns to false, then just add the columns manually:
datagrid.Columns.Clear();
foreach(DataColumn column in dataView.Table.Columns)
{
datagrid.Columns.Add(new BoundColumn {
HeaderText = column.ColumnName });
}
datagrid.DataSource = dataView;
This works fine. Why can't .NET do this with AutoGenerateColumns?
Why is the following asp.net code not including styling information when being rendered to HTML?
<asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="#333333"
GridLines="None">
<RowStyle BackColor="#FFFBD6" ForeColor="#333333" />
<FooterStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#FFCC66" ForeColor="#333333" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#FFCC66" Font-Bold="True" ForeColor="Navy" />
<HeaderStyle BackColor="#990000" Font-Bold="True" ForeColor="White" />
<AlternatingRowStyle BackColor="White" />
</asp:GridView>
Here is the HTML that is rendered:
<div class="AspNet-GridView" id="GridView1">
<table cellpadding="0" cellspacing="0" summary="">
<thead>
<tr>
<th scope="col">Name</th>
<th scope="col">Age</th>
<th scope="col">Sex</th>
</tr>
</thead>
<tbody>
<tr>
<td>Ronnie</td>
<td>25</td>
<td>M</td>
</tr>
<tr class="AspNet-GridView-Alternate">
<td>Tina</td>
<td>25</td>
<td>F</td>
</tr>
<tr>
<td>Lukus</td>
<td>4</td>
<td>M</td>
</tr>
</tbody>
</table>
</div>
There are no themes defined for this site. Any ideas what is going on? EDIT I created a new web site in VWD Express and copy and pasted my gridview code, which resulting in the following HTML being rendered:
<div>
<table cellspacing="0" cellpadding="4" border="0" id="GridView1" style="color:#333333;border-collapse:collapse;">
<tr style="color:White;background-color:#990000;font-weight:bold;">
<th scope="col">Name</th><th scope="col">Age</th><th scope="col">Sex</th>
</tr><tr style="color:#333333;background-color:#FFFBD6;">
<td>Ronnie</td><td>25</td><td>M</td>
</tr><tr style="color:#333333;background-color:White;">
<td>Tina</td><td>25</td><td>F</td>
</tr><tr style="color:#333333;background-color:#FFFBD6;">
<td>Lukus</td><td>4</td><td>M</td>
</tr>
</table>
</div>
Something is keeping styling information from being included in my original project.

Im trying to render a gridview control to a string as part of a confirmation email to be sent to a customer. When I try to render it, I get an exception.

The RenderControl() raises the aforementioned exception. Has anyone succeeded in doing something similar.
I am having an issue with the gridview in ASP.NET. Everything works well when running from IDE in both debug and without debug. When I publish to IIS I have a gridview that I use in two places. It works fine in one place but not the other. In one instance I am using an IFRAME tag to display the page that uses this data grid. When I first load it it works fine, I can click on a row. But after clicking on that row after the first postback, I can no longer get it to postback again on future clicks. I used firefly and after clicking the first time on the grid, the tags for the table are not rendered though I can clearly see the grid. Confused... Here is the rendered code before clicking on it using firefly. (oh yea, this gridview is also inside of an updatePanel) (In the below I replaced actual data with xxxx)
[Code]....
Below is the code after clicking on the grid.
<div id="UpdatePanel1">
<div style="background-color: white; width: 818px; height: 405px; overflow: auto" onscroll="GetScroll()" id="divFill">
<div style="padding-bottom: 5px; background-color: buttonface; width: 818px; height: 20px; padding-top: 5px" id="NavFoot" align="right">
</div>
Also, if I did not provide enough information let me know.

The above error occurs with gridview control , when used with template field columns with item template / and edit templates etc.
updating a row within gridview, at the time of loadiong it loads perfectly fined, but when tried to modify an existing row within gridview control, then it produces the error. Make sure the grid view control has to be a child control which manages the child table info with in a master form. to reproduce the above problem the grid view must be loading the child records info of a master within the masterform, meaning both master data and gridview data all to be managed in one single form.
I had to replace gridview control with datagrid and then it worked perfectly fine. I wasted almost 4 days of my time., there is no way we could figure out the problem. here is the full info of the problem.

I have 2 grids gvParent & gvChild I would like to filter gvChild when a row is selected in gvParent the linking fields are contractNo
I added a column for selecting:
<asp:TemplateField ShowHeader="False">

<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Select"
OnClick="LinkButton1_Click" Text="Select"></asp:LinkButton>
</ItemTemplate>

I know how to handle the filtering of the grid (create a criteria and set to rowfilter of the dataview) But, I dont know how to get the value of the column of the selected row.

I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.
Can i get the row selected in th GridView or DataGrid in ASP.NET?
View 1 RepliesI'm not asking as to how go about doing this, but just curious if its possible to list items in a data grid/ grid view as you would in asp.net websites, but in SharePoint using say web parts? Then be able to select a item in the grid and press a button that would then carry on out some task?

View 7 RepliesI am using ASPNET2008 I have been asked to replace DATAGRID with GRIDVIEW on WEBFORM1.ASPX.
For Pagination, I am having problem due to lack of knowledge to replace page 1,2,3,4,5,6,7 8, 0 with NEXT , PREV like I did it for DATAGRID. Have to use NEXT and PREV because the GRIDVIEW Pagesize = 20 while the rows from the TBLSALESTRANSACTION exceeded 350rows What I am trying to do is, each time the user click on either NEXT or PREV, This is what I want the GIRDVIEW to display. NEXT the GRIDView should display the next 20 rows and the LBLPAGE.text should display the page number of the current 20 rows, Eg. Page : 2 / 18 PREV the GRIDView should display the previous 20 rows from the current 20 row and the LBLPage.text should display the page number of the current rows, Eg. 1 /18.
Also, How do I determine logically whether it NEXT or PREV being clicked ? And how do I use this FLoadGridView to either display next 20 or previous 20 rows.

I have a datagrid that is displaying data that is being returned from a stored procedure. That works fine. The problem is that I want to do sorting. I know that there is sorting functionality in the grid, however, I don't want to go back to the server and get a new set of data. What I want to do is just re-sort the data that is already being displayed.
Basically, I couldn't not find an easy solution to this issue. I tried updating my dataGrid to a gridView control and even that (for my particular issue) was difficult. I wound up un-doing all the changes and just adding another grid that had just the data I wanted for the requirement. If anyone else has an issue like this I would recommend taking it out of a datagrid and writing it in jQuery. I could of written a table that had the data I wanted (and fully sortable using a plug-in mentioned below) in 15 minutes compared to the hours I spent trying to jam a square peg into a round hole.
I am upgrading some code from a previous version of .NET so I converted the datagrid that was there to a gridview. I need to get the index of the row clicked. It is not working. I have an outrageous number like 577 but there's only five or so rows in the grid. Is something left over that is screwing it up?
I am clicking the View Status link:
Code:
<asp:GridView runat="server" AutoGenerateColumns="False" Width="100%" ID="gvOrderGrid" AllowSorting="true" OnSorting="SortPageCommand" OnRowCommand="ProcessItemCommand"
OnPageIndexChanged="PageCommand" AlternatingRowStyle-CssClass="alternatingItemStyle" CssClass="dataGrid" HeaderStyle-CssClass="headerStyle" RowStyle-CssClass="itemStyle"
PagerStyle-CssClass="pagerStyle" PageSize="20" PagerSettings-Visible="true" PagerSettings-Mode="Numeric" AllowPaging="true" GridLines="None">

Shouldn't this line of code Dim index As Integer = Convert.ToInt32(e.CommandArgument) get me the row?
I have been trying to implement an extended GridView that eventually will include a panel with a number of filter options outside of the grid iteself.
As a test I have added a dropdownlist and a linkbutton but when these are rendered to the page they are rendered as plain HTML with none of the javascript or ids that are generated for server controls as a consequence the postback event is not fired when a dropdownlist item changes and the linkbutton is rendered as plain text.

Does any one know the way to convert the following from DataGrid to GridView?

I have a interesting problem and being relatively new to .NET I thought to try the forum for some guidance. I need to present information from a database, typical, but I need to create stand alone views of the data based on the "category" for the reported information. I don't know how many or how few categories I might need to generate but each needs to be displayed in its own datagrid or gridview. I did a prototype report where I could dynamically generate a variable number of columns in a generic datagrid already placed on the page based on the database but the user "changed their minds", also typical, and want a different view (actually views). Does anyone have any thoughts on creating anywhere from 1 to a dozen (or more) datagrids in the code behind and then pushing them out to the aspx page for the user? Can you dynamically generate datagrids and gridviews on the fly? Or would you need to?
View 3 RepliesI am going to have a page that list an (image, description, category) this needs to be an editable list (the user should be able to edit description or select a cateogry from a dropdown or delete the whole image). lets say I need to display 20 rows per page.here are my questions:1) should I use datagrid, gridview or datalist?2) would PagingBulletedList works well with any of the above control3) when I go to the database to get the rows , since i am going to have 20 items per page should I just bind the control with all the rows or should I just display the first 20 items and when the user click page 2 i go to the database to bring the second set of 20 items?
