I am using the ASP.NET3.5 gridview control in a new project. My problem is that the gridview presents data in basic tabular format, whereas I want a grid with row header / grouping behaviors. An example of this would be Outlook web interface, which can group emails by date, as well as allowing you to select individual emails to display.
My problem: I can't see how this could be easily done with Gridview? I did find a product called Telerik that has a seemingly fancy Gridview, but I am hesitant to spend money on a single components that now also locks me into a third-party framework...

I am working on charts with ms chart 3.5 control my question is I have to display legends of pie charts in tabular form. Which will contain the color used for different points and x values and y values. I managed to show the colors and x values but not able to show the y values. I am giving the code also. Example of x and y values are: xvalues- InCorrect YValue- 5 xvalues- Correct YValue- 10 xvalues- UnAttempted YValue- 15
Here is the code used to bind legend values.---- LegendCellColumn firstColumn = new LegendCellColumn(); firstColumn.ColumnType = LegendCellColumnType.SeriesSymbol; firstColumn.HeaderText = "Color"; firstColumn.HeaderBackColor = Color.WhiteSmoke; Chart1.Legends["Default"].CellColumns.Add(firstColumn); // Add second cell column LegendCellColumn secondColumn = new LegendCellColumn(); secondColumn.ColumnType = LegendCellColumnType.Text; secondColumn.HeaderText = "Name"; secondColumn.Text = "#LEGENDTEXT"; secondColumn.HeaderBackColor = Color.White; secondColumn.Alignment = System.Drawing.ContentAlignment.MiddleLeft; Chart1.Legends["Default"].CellColumns.Add(secondColumn); // Add header separator of type line Chart1.Legends["Default"].HeaderSeparator = LegendSeparatorStyle.Line; Chart1.Legends["Default"].HeaderSeparatorColor = Color.FromArgb(64, 64, 64, 64); // Add item column separator of type line Chart1.Legends["Default"].ItemColumnSeparator = LegendSeparatorStyle.Line; Chart1.Legends["Default"].ItemColumnSeparatorColor = Color.FromArgb(64, 64, 64, 64); // Set Min cell column attributes LegendCellColumn minColumn = new LegendCellColumn(); minColumn.Alignment = System.Drawing.ContentAlignment.MiddleLeft; minColumn.Text ="#TOTAL{N1}";
I want to show the individual value of each data point is there any idea how to show the Yvalue of each datapoints minColumn.HeaderText = "Questions"; minColumn.Name = "Questions"; minColumn.HeaderBackColor = Color.WhiteSmoke; Chart1.Legends["Default"].CellColumns.Add(minColumn);
I have to show progress bar in datalist and having following scenario:
I am collecting response for the questions For each answer, total no of responses and their respective Percentage(%) is calculated
Now I have to show this % progress in progress bar
means if a answer have 100% response then progress bar show 100% (100% filled) if it have 50% response then only half of progress bar is filled (50% filled)and so on. response is calculated upto one decimal places(like it can be 33.3% or whatever)and respective % have to be shown in progress bar
So I have to create progress bar dynamically for each response %
How to display % in progress bar, I am using asp.net 2.0 with C#..
I have written some code to dynamically generate template columns for gridview which works well. However, each cell in the gridview has to be a linkbutton, which when clicked does a db update and redirects to a specific url with some parameters in it.
I have attached a click event handler to the linkbutton in the InstantiateIn method but the event does not seem to fire.
//Dynamically creating the Grid protected void btnAnalyze_Click(object sender, EventArgs e)

I am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here

Can someone suggest a good link, example or suggestions to make it better.
I'm working on a small standalone .NET app needs to refer to some tabular data and its only just selects and at most these tables have 250 records. Previously developers have used a SQL server database. Would I get a performance advantage if I simply convert the table data to XML and read from that? Also is there any kind of performance advantage over keeping database files in the App_Data folder for ASP.NET and attaching them dynamically as opposed to managing them separately? And this is probably a silly question, but if I do it that way does it mean that I don't have to install SQL server separately on the client's computer?
