I have a DataGrid that is bound to a data set. Down column 1, I need each row in the column to be a link to another page or just plain text - which I can determine post-bind.
e.g.
<table>
<tr>
<td>Row 1</td>
</tr>
<tr>
<td><a href="page2.html>Row2</a></td>
</tr>
</table>
Can this be done in a DataGrid? I need to give the user an indication in the cell that there's a link versus no link to another page.
I have certain columns in my DataSource such as "ID", "StartTime", "EndTime", etc.I would like to present them a bit differently in the listview.for example, I want to present the "StartTime" and the "EndTime" in ("hh:mm:ss") form, and would like to show only IDs smaller than 10.I thought about writing the code in
protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
{
}
I have no problem writing the conditions in code behind, but the question is:since the ListView1_ItemDataBound event handler is fired for every column, how can I know in which one I am concerned, and so which condition to use?for example, if it is a "StartTime" then I want to have (DateTime)item.ToString("hh:mm:ss"), but if it is "ID", I only want to check if ID<5.
I have a stored procedure that returns a dataset with a different number of columns and different column names depending on user input. How can I use this with a GridView? Normally I define the columns beforehand in a static fashion, but, have never done a dynamic dataset like this.
View 1 RepliesIn my web forms application I have a site.master page with an update panel (Java Script ToolKit). Inside the update panel I have a survey and a columns chart to show its results. The chart properties are
visible = false
ImageStorageMode = UseImageLocation
RenderType = ImageTag
When the user votes, his/her vote is stored in a sql server table The chart is rebound to its data source
The chart visibility is set to true and the survey's questions are hidden. I've been trying to set the columns for the maximum and minimum values to a different color using the code I found in "Samples Environment for Microsoft Chart Controls" [URL] under Working with Chart Data Data Manipulation Finding Data Points Find Maximum and Minimum Values:
[Code]....
I have not got the columns to change their color. I have put the code inside every event handler I could think of (after it failed to work inside the page load event handler): Inside the chart Init, load, and pre_render handlers. Inside the click event handler for the voting button (before and after I call the chart.DataBind() method). Inside the page pre_render handler. Inside the ToolKitScriptManager pre_render handler. I checked the code behind the environment samples. All, to no avail.
URL....According to my requirement based on columns value button text is changing. But I want to apply some action on it. Means previously, I used Command Name for a button and in Row Command event I have written the code which was working. But now, after writing this code I am getting an error message. Because now the button is converted into template field.
View 1 RepliesI created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:

View 1 RepliesI haven't had any luck finding the answer yet. My problem is that I want to be able to update the dataformatstring on a gridview column at runtime. For example, I switch from displaying # of units to cost of said units... and I want to change the format of the column to {0:c}. It seems like it should be a simple task.

I'm binding a gridview from a webservice with 30 columns and 10 rows, I need to print the same in a PORTRAIT, for that i decided to display columns as rows and
rows as columns like below:
EMP1 1 2 3 4
EMP2 1 2 3 4
How is it possible to change the displayed order of columns from a DataTable?
For example, dataTable "dt" contains two columns "a" and "b". I bind it to a GridView like this:
gridView.DataSource = dt;
gridView.DataBind();
But I'd like the GridView to display "b" first (leftmost).
Important point: I'm using this to export to Excel and there's no actual output to screen, using:
HtmlTextWriter htw = new HtmlTextWriter(sw);
gridView.RenderControl(htw);
I have a question, I have a gridview that shows a red balloon as imagebutton in one of the cells. Now i want to be able to let a users press the button, write a value in a record in the database and then change the red balloon to a yellow one. When the user wants (at any given time) wants the undo the value again the record should be rewriten again and the yellow ballon should be red again. Any tip is more than welcome :)

im building a simple message messenger web application, i currently have a column in my database dedicated to the status of a message. Its bound to the third column in a datagrid.
After converting the column to a TemplateField and using a Label to fetch the data how do i change the text from the database to a small message, e.g. if the data in the database (as an interger) is 0. how do i change the interger to a string to display "UnRead". Do i need to do this during the databinding call or after the grid has been databound?
I know it would be easier to use a boolean and checkbox control but the interger column represents more values than true or false.
I have a details view in asp.net which I am dynamically replacing some of the controls using code behind (e.g. converting some text boxes to dropdowns).

I can populate the dropdown with the current value from the database but cannot find how to save a new value on updating the detailsview.

I have a gridview which shows the contents of the shopping cart. The qty cell is a template control bound to the qty field in the datasource. My ideal scenario is to have the user highlit the qty, write the new one and press 'enter' to update the sqldatasource but this may not be possible.
My second chose is an Update button to update the data but this erases the data from the other fields not listed as key.
I have tried the edit and update functions but then all fields are editable and I dont't want that, just the qty cell. If I change the read only atrribute to true on the ones that I don't want edited, then it erases the information from those fields.

First off, sorry if this is in the wrong section. I have a gridview that loads from a SQL database. It has three columns, the first being a template column with a checkbox, the second being a name from the database, and the third being a field from the database related to that name. (the third column is empty). I want to be able to click on the check box in each row, and automatically have the third column populate with data that the user can select from a drop down list at the top of the screen or something. I am using VB, and I basically just need a way to make this checkbox, add a value from somewhere into the database. (Also, I know that I can just use Edit in the gridview to change data, but there will be a long list, and that way gets quite time consuming) I hope this makes sense, if not I can try rewording it.
View 5 RepliesI have created a FormView whose defaultmode = "insert". When loaded the FormView displays the InsertItemTemplate. At the top of the page is a DropDownList used to select Clients. I have added a list Item to the DropDownList with value = "0" and text= "Select Client" option. So the Page is in Insert Mode. SO FAR EVERYTHING IS AS EXPECTED.
When I select a Client from the DropDownList, the page remains in Insert Mode (Don't understand why? ) Could it be the default Mode setting? So I added the following vb code.
Protected Sub ddlSelectClient_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlSelectClient.SelectedIndexChanged
If ddlSelectClient.Text <> "(Select Client)" Then
If FormView1.CurrentMode = FormViewMode.Insert Then
FormView1.ChangeMode(FormViewMode.Edit)
End If
End If
End Sub
So after an existing Client is selected, the FormView Mode should be changed to EDIT. AND INDEED THE EDIT ITEM TEMPLATE IS DISPLAYED.
Ah but life is not so simple (after all this is a Microsoft Application). So I enter data in some fields and click the [Update] Button.
Then I get the following message:
FormView 'FormView1' must be in edit mode to update a record.
THe FormView displays the Edit Template, the Update and Cancel Buttons are displayed. All this should mean I am in edit mode.
Just call me FrankenSoft !@#$%^^& or is it MicroStein?
Oh by the way I'm using Linq to SQL data sourcess. Should I be? I'm having a lot of problems with the FormView using Linq.
Do anyone knows how to change the x-axis and y-axis of graph using dropdownlist which is being binded to a datasource and group according to years/months?
