Gridview, datatable, selected row

Hello!
I am using a gridview like this:

private void LoadGrid()

{

DataTable dataTable = new DataTable();

DataColumn itemIdColumn = new DataColumn("ItemId", typeof(int));

DataColumn itemCodeColumn = new DataColumn("ItemCode", typeof(string));

DataColumn itemNameColumn = new DataColumn("ItemName", typeof(string));

DataColumn sellPriceColumn = new DataColumn("SellPrice", typeof(decimal));

DataColumn vatValueColumn = new DataColumn("VatValue", typeof(decimal));

DataColumn itemTypeColumn = new DataColumn("ItemType", typeof(int));

dataTable.Columns.Add(itemCodeColumn);

dataTable.Columns.Add(itemNameColumn);

dataTable.Columns.Add(sellPriceColumn);

dataTable.Columns.Add(vatValueColumn);

dataTable.Columns.Add(itemTypeColumn);

dataTable.Columns.Add(itemIdColumn);

dataTable.BeginLoadData();

var lst = _relatedItemBc.GetItemsForMainGrid(FilteredItem);

for (int i = 0; i < lst.Count; i++)

{

DataRow row = dataTable.NewRow();

row["ItemCode"] = lst[i].ItemCode;

row["ItemName"] = lst[i].ItemName;

row["SellPrice"] = lst[i].SellPrice;

row["VatValue"] = lst[i].VATValue;

row["ItemType"] = lst[i].ItemType;

row["ItemId"] = lst[i].ItemID;

dataTable.Rows.Add(row);

}

dataTable.EndLoadData();

rbcDataGridViewMain.MasterTemplate.BeginUpdate();

rbcDataGridViewMain.DataSource = dataTable;

rbcDataGridViewMain.MasterTemplate.EndUpdate();

}

How can i get the informations for the current row, the row i have selected?

Thank you!

Gridview Combobox Column

Hi There,

I have a combobox column in a gridview, the combobox has a datasource set to a list of objects returned from my database. One of these items in this datasource is an "Other" item. I am looking for a way so that when a user clicks "Other" as the selected item the combobox can be edited and a new value inserted into the datasource.

Can anyone offer any advice on the best way to do this?

Many Thanks For The Suggestions/Help?

[Solved] RadGridView ExportToExcelML

We are having two different issues with exporting using the Export To ExcelML.

First I'll show the code that we're using:

Me.RadGridView1.Columns("Date"

).ExcelExportType = DisplayFormatType.Custom

Me.RadGridView1.Columns("Date").ExcelExportFormatString = " mm/dd/yyyy "

Dim exporter As Export.ExportToExcelML = New Export.ExportToExcelML(Me

.RadGridView1)           

exporter.FileExtension =

"xls"

        

exporter.HiddenColumnOption = HiddenOption.DoNotExport            

exporter.ExportVisualSettings =

True

         

exporter.RunExport(fileName)

The first issue. In the database we have the Date column as a DateTime datatype. I have the Custom ExcelExportType set to only show "mm/dd/yyyy" When it exports it will show up with that format - but the data still has the time included with it. We need it to only export the date, not the time.

The second issue comes from trying to open the exported file. Every time we try to open the .xls file, a warning comes up
"The file that you are trying to open, 'Filename.xls' is in a different format than specified by the file extension"
Everything still worked after that - but it is a little annoying have to go through that each time.

Please let me know of any suggestions.

Thanks.

Creating columns in manual way (using designer) make them only visible in Designer.cs file, because declaration is in InitializeComponent() function.

RadTimePicker Tab into Minutes

When my users are changing the hour in the time picker by typing in the numbers, they would like to be able to navigate to minutes when they press the tab key.

The desired functionality happens when they press the arrow right key, but they would like it to happen for the tab key as well.
I could not figure out how to make this happen. I tried looking in properties and I tried to intercept the tab key on all of the key events, but the tab key would not fire any key events before it went to the next control.

[Solved] Demohub Sample question

Hi,

I'm trying to learn more about the metro style and and panorama using the demohub apps example. My question is: how are the margins set when the different controls load after clicking on the tiles such as "Gridview" example. I have created my own control and loading it from the main tile screen, however I would like for the control to fill all the white space below the header.

Any pointers would be greatly appriciated!

Thanks,
Ronny

Set ToolTipText after adding row?

With RadGridView, Is there a way to set the ToolTipText value for a certain cell immediately after adding a row? For example:

int rowIndex = RadGridView1.Rows.Add("column1Text", "column2Text", "Column3Text");

RadGridView1.Rows[rowIndex].Cells["FirstColumn"].?? (ToolTipText property) = "ToolTipValue";

Is there any way to set the ToolTipText property for a certain cell of that row?

Thanks,
--Jason
