I have a grid (Q2 2014 SP1) with several columns and one checkbox column.  The checkbox is the only information that can be modified by the users.  Now, depending on the checkbox state, I paint the row using this code (where "IsConcilie" is the checkbox's column name):

if (row.Cells["IsConcilie"].Value.Equals(true))
{
rowElement.DrawFill = true;
rowElement.GradientStyle = GradientStyles.Solid;
rowElement.BackColor = Color.Gray;
rowElement.ForeColor = Color.White;
}
else
{
rowElement.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
rowElement.ResetValue(LightVisualElement.GradientStyleProperty, ValueResetFlags.Local);
rowElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);
rowElement.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local);
}

The problem I have is when one of the cell is clicked, the cell is selected and painted using the default colors which makes the cell hard to read because it keeps my foreground color setting.

Since only the checkbox can be modified, is here a way we can prevent the selected cell to paint using the default painting behavior?  Or how can I handle the painting of the cell myself and bypass the default settings?  Or even, can we make the rows non-selectable?

Thanks.

Trying to implement this feature-

http://feedback.telerik.com/Project/154/Feedback/Details/112143-fix-horizontal-scroll-bar-should-appear-when-auto-size-columns-mode-is-enabled-a

With ColumnGroups and it does not seem to honor the minimum column widths.  Is there a way to implement scrolling when using auto sized columns when the view has been put into ColumnGroups?

 

I using a demo copy of your Winforms Rad Control for testing and evaluation.  My issue is when I'm using one of your radforms my data sources window will not allow me to drag and drop Entity framework 6 data sources onto your forms. Can you tell me how to resolve this issue please ?

Hi. 
I Have a radGridView, i am trying to find the TextChanged Event of a cell, in which i want an event to happen while the user is typing inside a cell while text is being changed.

How to find it?

Thankfully yours.

Hello,

I upgraded the Telerik WinForms to 2014.2.715 version.
The upgrade results to all my forms containing the radtextboxes and raddropdownlists with Anchor property set to `Right` stops working properly.

1. The affected control (e.g. radtextbox) shall be placed on a UserControl control directly or on a panel.
2. Its anchor property must contain Right (eg Top+Right+Left)
3. The UserControl control must be placed on a Telerik RadForm.

After starting the app the radtextbox ignores the anchor=right and leaves the form's boundaries.

Resizing the UserControl in the designer works fine. Previous release (2013.3.1127) doesn't contain this problem. The problem appears after upgrading to 2014.2.715.

As I understand it is old bag reincornated :) The problem is the same as described here: http://stackoverflow.com/questions/9604605/user-control-keeps-stretching-once-dropped-on-form

Hi to all,

I trying to copy from one gridview that has 4 columns and paste another gridview that has 3 columns.

Now, in RadGridViewPasting of destination GridView I wrote this code, those gridviews are into Windows dialog that called from main Windows with ShowDialog mode. But this code generate an error.

 If I compare ContainsData in incoming and ContainsData in outcoming are formally correct.

What's up?

Hi,

I have a grid with 3 aggregate footers, when the  user groups on a particular column I’m adding
the aggregate  values to the group
header, which works fine.

But I cannot get the text to align , I have tried to pad the
text with spaced with no success, here an image…


What I’m hoping to do is basically align / give the illusion
of  4 columns in the header,  one for the column title the other 3 for each  aggregate value.

Here's some code:

private void gviTicketSummary_GroupSummaryEvaluate(object sender, GroupSummaryEvaluationEventArgs e)
{
int i = 0;

if (e.SummaryItem == null)
return;

if (e.SummaryItem.Name == "Site")
{
int count = e.Group.ItemCount;
decimal PlannedQty = 0;
decimal ActualQty = 0;

foreach (GridViewRowInfo row in e.Group)
{
PlannedQty += Convert.ToDecimal(row.Cells["PlannedQty"].Value);
ActualQty += Convert.ToDecimal(row.Cells["ActualQty"].Value);
}

string sPlanned = PlannedQty.ToString("#,##0");
string sPlannedNew = PlannedQty.ToString("#,##0");

if (sPlanned.Length < 20)
sPlannedNew = sPlanned.PadRight(20, ' ');

string sActual = ActualQty.ToString("#,##0");
string sActualNew = ActualQty.ToString("#,##0");

if (sActual.Length < 20)
sActualNew = sActual.PadRight(20, ' ');

string site = e.Value.ToString().Trim();

string siteNew;
if (site.Length < 20)
{
siteNew = site.PadRight(20, ' ');
}
else
siteNew = site;


string Header = string.Concat(siteNew, " Planned Tonnes :", sPlannedNew, "Actual Tonnes : ", sActualNew);

// e.FormatString = String.Format("{0}Planned Tonnes : {1} Actual Tonnes : {2}", siteNew, sPlannedNew, sActualNew);

e.FormatString = Header;


}

} 

Hope this makes sense

 

Thanks

I'm looking for some clarification on the Bin and Bin40 directories.

I a previous thread there was mention that Bin was for .net 2.0 and Bin40 was for .net 4.0, but that doesn't really explain how the directories should be used. We build under .net 4.0.  Recently in our projects, we somehow found some references to assemblies in the Bin directory that were causing exceptions.  We never reference anything in that dir... at least not intentionally. 

Can someone explain the difference between what's in the Bin and Bin40 directories, why they exist and what developers need to know about them?   Thanks.

how can i use a binding source to bind values to radColorBox  while binding source is list of string of color names

Hi All,

in the former control I used the TextChanged Event with others to set a dirty flag providing the user a message to save his changes before leaving the Editor. In the current control the Event is not firing.

As an alternative I used the ContentChanged Event if the user changes any text. But this Event has the drawback that is fired after loading the form before the user had any chance to enter any character.

What can be done to get that scenario working.

 

Best Regards

Herbert
