Column In DataView Not Rendering When Databound To DataGrid (or RadGrid)?
Sep 7, 2010
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:
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)
I am using VB. ASPNET2008 to develope Web Application. I am not sure whether to insert control DATAGRID or DATAVIEW. Also, what Reference Library am I supposed to use in order to use the Control.
using Telerik RadGrid* in a LINQ context, with ASP.NET/C#, how to truncate text to a maximum length when displaying in columns? By maximum, I mean if original string's length is shorter than the specified maximum length, no errors will raise.I have seen many examples of this on the net, but it seems that the Container.DataItem used to achieve this is different when using LINQ. Sometimes we see DataItem as a method, sometimes not. Examples are usually using a DataSet.Here's an example found (source) :
I'm getting a blank column when switching to another page using the default pager in the telerik radgrid. As data for each row, it shows the type of data i am using for the rows (SearchRecord)
Anyone have any clues as to why this may be happening? It doesn't show up on initial population of the grid, but only when I do paging. My columns are built dynamically but i confirmed that when my columns are built, they are the correct number.
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?
I wanted to ask what is the best practice to manage width of the radGrid.
For my application most users are running 1280 x 1024 so I would be happy to set my overall grid width to 1100. However, depending on the form in use, I sometimes have horizantal scroll bars. To solve this, I have been playing with the width of the grid, and also I have played with setting the itemstyle-width for one or two columns. Sometimes I accidentally get it right, and sometimes it is not quite right.
What is the best way to manage this? Do I set the grid, and then all columns, or just the grid, or just the columns? I guess there is a best practice, so just wondering how you handle it,
I've got a datagrid which i wanted to sort, since i dnt have much knowledge of .Net, so what i did was to save that datagrid in a DataTable, then again save the same DataTable in a DataView, then apply sorting on that DataView. this is the code, and its working fine.
but the issue comes when the i try to sort the Date Column, the dates are in MM/DD/YYYY format, so if i try to sort the date column, the dates are sorted on month basis, rather than year basis. now i cant change the date format, is there any way to sort dates in DataView?
Using VS2008, and Telerik radGrid version 2010.1.519.35
I have a about 50 DNN modules using telerik radgrid and I need to display my dates in dd/mm/yy format. It is possible to do this easily in view mode, but when I switch to edit mode, it is more of a struggle. I can write a snippit of code to reformat the displayed date values to dd/mm/yy, but for inserts the user must enter mm/dd/yy.
IOW, I need to change the culture of the form to en-GB culture.
In my DotnetNuke App, I have made a change to the web.config, but it still assumes en-US format.
I am not sure whether I need to set this at web.config level, page level or at the column within the control.
I know how to do this in a datatable but I would just like to learn how to do it in a dataview.
I have a dataview which is used to populate a gridview. It has the following column
userid Location 123 New York 124 Chicago 125 London
Now, I would like to know how to determine the 124 row and highlight it to a blue in a dataview used to populate a gridview. kindly note, i can do this in a datatable but not a dataview. I would like to learn how to do it in a dataview.
I am having one column in each row of my radgrid in which i want to show an image. I am getting values from database saying 1,2 for that particular column and for each of these values i want to show different images for different values. For Example if i am getting 1 from database i want to show "roseImage" and for 2 i want to show "lotusimage",
I have the following code reading in my xml file and sorting it by ID:
Dim ds As New DataSet ds.ReadXml(Server.MapPath("/posts.xml")) Dim dv As New DataView(ds.Tables(0)) dv.Sort = "id desc"
The only problem is that it isn't sorting it numerically (it's sorting it alphabetically 1, 10, 11, 2, 24, 3, 4...). It appears as though I have to convert that column into integers, but I haven't been able to figure out an efficient way to do that.
im ds As New DataSet ds.ReadXml(Server.MapPath("/App_Data/posts.xml")) 'ds.Tables(0).Columns(0).DataType = TypeOf(Decimal) Dim dv As New DataView(ds.Tables(0)) 'dv.Sort = "date"
How can I add a column, and then under that column fill in the data based on a databound column? Please read my code below. The code below adds a row like I want, but adds another cell.
Code: Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound If (DataBinder.Eval(e.Row.DataItem, "court") = "D072") Then
I have a grid containing images loaded from database. the images are displayed in the order as they are stored in the database. Is there any way to change the order of the images manually once after they are uploaded to the database.. the admin before publishing the images to front end, should be able to arrange the images as he/she wish and then finally stores them in database.
I have given an access to stored procedure, which i'm not able to edit. This Stored Procedure returns a Table with 2 Column, what I did is set a GridView's DataSource using SQLDataSource in this stored procedure. but I want this GridView to Sort an specific column to descending whenever this GridView Loads.
I have "Order" object with Columns Ticket,OTP and CustomerName etc.Intially on DataGrid, I'm binding Ticket only , when user clicks on "Column Chooser" button, another windows appears to pickup CustomerName,OTP columns to add specified column dynamically on Datagrid. Environment : Asp.net ,C# with Object Data source
Public Class Order { publc void Order() { } public string Ticket { get { return this.strTicket; } set { this.strTicket = value; } } public string OtpNumber { get { return this.strOtpNumber; } set { this.strOtpNumber = value; } } public string CustomerName { get { return this.strCustomer; } set { this.strCustomer = value; } } } }
I have a condition on which i have to set the column of the datalist at run time.IT may be 2,3 or 4 at run time. How i do it. plz replay as soon as possible.
Is this possible that on the item bound event i set the html <tr><td>.
I have a stored procedure (For Eg: sp_GetAvlData) that accepts a number of parameters, 3 of which are TimeFrom, TimeTo (as varchar) and TimeInterval (as int), formulates a Dynamic query and executes itself. So for instance, if I call the proc as follows:
[code]....
dtAvl is the datatable containing the results of my stored procedure.
The next step for me is to make each of the cells (except the cells in the first column) as a Hyperlink so that when clicked upon a cell, it populates 2 textboxes with the selected Timeslot and Name or ID (ID field is not displayed in Gridview). The textboxes are located on the same page but outside of the Gridview control.
The Challenge that I'm facing out here are:
1) As you can see, the field names being generated are not fixed and I have no control over them.
2) Because the field names are not fixed I'm not sure I can implement this using the Templatefields or BoundFields of Gridview.
Is there any way to achieve the Hyperlinking of these cells within the Gridview?
