[Solved] How to set errortext when adding a record

In my cellValidating event, I validate the field and set the errortext if invalid. However, if I am adding a new record, the row is not GridViewDataRowInfo, which has an errortext property, but GridViewNewRowInfo, which doesn't. Is there any way to set the errortext for the row?

[Solved] Issues with RadGridView column data types

I have been using the wizard to create a RadGridView on a VB .NET 4.5 WinForms application. Going into the "open Property Builder" aspect of the wizard. I need to create a column of "dates" and I've tried several ways to do it.

I tried using the GridViewDateTimeColumn, figuring there was a way to turn off the "time" portion of it. I cannot find it. I feed the date from the database as a "Date" format, so the cell displays "9/25/2013 12:00:00 AM" instead. There were additional problems with the mask, but I can't remember what they were off-hand.

So I tried using the GridViewTextBoxColumn and discovered that it will insert the date, but that it does comparisons as strings. And in one of my gridviews, it still has the time portion even though I even parse the data using the .NET parsing for date only!

The data coming from the database is "CONVERT(DATE, DtField)" so I know it should be coming back as a date only.

I even looked into building the gridview programmatically, but I can't find any entry for a GridViewDateColumn (or something like it) anywhere.

What am I missing? Is there no strict "date" only column or ability to adjust the date/time column to date-only?

Oh and one more thing: it appears that even if I handle the cell_doubleclick event of the gridview (the intent is to insert the current date on doubleclick of the cell), the gridviewtextboxcolumn cell on the inside does not allow you to double-click it -- is it treated separately? I haven't tried to fix this yet, as I'm fixing other bigger issues, but I'm wondering if there is a way to let the event bubble down or to grab it bubbling up? (for that matter, I haven't seen any way to grab events bubbling up... do they even bubble events up out of the RadGridView?)

Hierarchy grid view on more than 2 levels not working

Hi,

i'm currently trying to do a hierarchy grid view on more than 2 levels and it isn't working.

The grid is working fine if I use two levels but as soon as i add another one the expand on the grid show nothing after the second level

Here's the code of the grid :

<telerik:RadGrid ID="rg_VL" runat="server"

DataSourceID="SqlDataSourceCODPRO1"

Change Multiple radMulticolumncomboboxes

I have a "C#" application that is using the Microsoft.VisualBasic.PowerPacks.DataRepeater. This control mimics the microsoft access continuous form. Within the datarepeater I have 3 radMultiColumnComboBoxes. The first radMultiColumnComboBoxes is populated on load. The 2nd radMultiColumnComboBoxes data is based on radMultiColumnComboBoxes1 and the same goes for radMultiColumnComboBoxes3 to radMultiColumnComboBoxes2.

private void dRepeater_ItemCloned(object sender, DataRepeaterItemEventArgs e)

{

RadMultiColumnComboBox multiCBSup = (RadMultiColumnComboBox)e.DataRepeaterItem.Controls["cbSup"];

dtSup = dtCategories.Select("id=1").CopyToDataTable().DefaultView.ToTable(true, "value", "text");

multiCBSup.DataSource = dtSup;

//Category

RadMultiColumnComboBox multiCBCat = (RadMultiColumnComboBox)e.DataRepeaterItem.Controls["cbCat"];

dtCat = dtCategories.Select("id=2").CopyToDataTable().DefaultView.ToTable(true, "supcat", "cat", "value", "text");

multiCBCat.DataSource = dtCat;

multiCBCat.DisplayMember = "cat";

multiCBCat.ValueMember = "cat";

}

This code should populate each row of controls with it's own data. So when I change combobox1 in row 1 I don't want to change combobox1 on every row.

private void dRepeater_DrawItem(object sender, Microsoft.VisualBasic.PowerPacks.DataRepeaterItemEventArgs e)

{

DataRow dr = (DataRow)dtAct.Rows[e.DataRepeaterItem.ItemIndex];

RadMultiColumnComboBox multiCB = (RadMultiColumnComboBox)e.DataRepeaterItem.Controls.Find("cbSup", false)[0];

}

I'm not sure at what point I can get the value of the previous combobox.

Thanks for any help

Tri State Check Box Performance Issues

Hi,

I'm using your WinForm treeview. I am populating the nodes using the NodesNeeded event. LazyMode is set to false and AutoCheckChildNodes is set to true.

Our data includes about 10 root notes. Some of the notes have over 30 000 nodes (many are parents with children). If we tick the root node, the tri state check box applies checks to all child nodes and ends up taking over a minute in some cases. If I disable AutoCheckChildNodes it doesn't appear to make any difference. If we just browse through the nodes and keep expanding different children, there is no issue, only when the status of a check box changes.

Ideally we would like to see the tri check status to persist but it doesn't need to update children items until they are open.

Thanks!

[Solved] RadRibbonGroup or Tab UserControl

Hi I am trying to determine how I would need to go about encapsulating a Ribbon Tab so that it can be used in several different places, otherwise I will have to write some slightly unpleasant code for determining the context of the contextual tab and making the buttons interact accordingly.
