Greetings!

I'm having an issue with a RadGrid using an EditFormTemplate; whenever I click my edit button on an item of this rad grid, the item goes into edit mode fine and my controls appear below them item. However, when the CSS for the row being in edit mode gets applied, it adds some peculiar artifacts to my grid. I get a blue line about 15 lines of text from the top of the item being edited. It's worth pointing out that the varchars being exposed by this grid are very large, which might have something to do with the issue; it only occurs when modifying an exceptionally long list of codes.

Please find attached screenshots of the problem behavior.

Screenshots include a before and after [edit button clicked] of the item in question, and the behavior exhibited.

It sort of hangs there, strangely in the middle of the original radgrid item. These elements don't appear to be actual controls; they seem to be part of a repeating background being applied by the CSS for an edit form item.

Here's my markup for the grid in question:

And here is the CSS which appears to be giving me trouble, pulled from dev console. The offending line is commented out. Disabling that attribute makes the coloration of the edit form item go back to default, but removes the garbage repeating x.

I can probably override it by "cancelling" the class in some way, but would honestly prefer it perform the coloration as it intends to, without the garbage.

Any assistance would be appreciated.

I i need to be able to access the text boxes within my form popup on rad grid I have tried the usual find controls but to no avail it always returns null. I cannot do it in itemDatabound as I am using a function in my dal which I need to pass the raw value to.

It is txtSubjectNotes.Text i require to access and Notes textbox Please can you advise also how can i close the popup from this button. Many thanks.

This is really minor, but in the example below, I get Visual Studio warnings that both Calendar and DateInput don't have runat="server". In looking online, I've seen examples where they exist and don't exist, so I'm assuming it doesn't matter. If that's the case, I'll add runat="server" to cut down on all my warnings, but I wanted to double check in case there's any reason not to include runat="server".

Hello,

I'm working on mapping column data to RadHTMLChart control & I'm running into a label display issue. One of the column colors that is used by my graph is black & it makes the tooltip label difficult to read since it also defaults to black. Is there a way to determine what color the column will be when the color for the column is set dynamically so that I can update the black column's tooltip label color? 

Thanks,

Hello,

I am creating a pie chart with three items

Responded/ Responded with comments/ Not responded

                 DataTable dt = GetDataTable();

                PieSeries chartData = new PieSeries();
                PieChart1.ChartTitle.Text = "Title";
                chartData.StartAngle = 90;
                chartData.LabelsAppearance.Position = Telerik.Web.UI.HtmlChart.PieAndDonutLabelsPosition.Center;

                SeriesItem item = new SeriesItem();
                SeriesItem item1 = new SeriesItem();
                SeriesItem item2 = new SeriesItem();

                foreach (DataRow row in dt.Rows)
                {

                    if (row["Responded"] != null && Convert.ToBoolean(row["Responded"]))
                    {
                        i++;
                    }

                    else if (row["Respondedwithcomments"] != null && Convert.ToBoolean(row["Respondedwithcomments"]))
                    {
                        j++;
                    }

                    else if(row["Responded"] == null)
                    {
                        k++;
                    }
                }

                chartData.LabelsAppearance.DataFormatString = "{0}";
                chartData.TooltipsAppearance.DataFormatString = "{0} ";
               
                
                item.Name = "Responded"; 

                item.YValue = i;

                item.BackgroundColor = System.Drawing.Color.YellowGreen;

             
                item1.Name = "Responded with comments";              
                item1.YValue = j;               
                item1.BackgroundColor = System.Drawing.Color.PaleVioletRed;
                

                item2.Name = "Not Responded";               
                item2.YValue = k;            
                item2.BackgroundColor = System.Drawing.Color.LightYellow;


              chartData.Items.Add(item);
                chartData.Items.Add(item1);
                chartData.Items.Add(item2);
               
              

                PieChart1.PlotArea.Series.Add(chartData);

Each time the chart refreshes to get the new data , the series name adds up so and I am also not sure that I am doing it the right way , please help!

I'm trying to bind to a templated column with a radDropDownList control in it. I am using editmode=batch on the grid. So when editing no events are fired server side.

How do I go about binding to the dropdownlist when the grid is populated server side. I tried binding to the dropdownlist when the grid is built server side in the itemdatabound event but the e.Item.FindControl("radddlParameterId") does not find the control.

I want the grid to show text and then when edited switch to the populated dropdownlist that the user can select from.

Thanks,

Steve

Hi,

I've looked at a few examples of performance improvement for grids that deal with lots (160K) records.  I haven't seen anything yet that looks at using the OFFSET/LIMIT functionality that you often see with web services.  Why is that?

It strikes me that if you can do it for web services then the standard grid should be able to cope with this,  performance would be dramatically improved.

Anyway if anyone has a good example of using a radgrid with OFFSET/LIMIT interfacing to a stored procedure I'd be very grateful to get a pointer to it!

Regards

Jon
