Grid Control: Doubt

[Pavithira]

Hi All,

I am using Syncfusion Grid control. I have to use radio button in a column. I referred the examples and tried using “StringCollection” function. Now I have to create choicelist related to column. The users will be provided with a list of option in a column as shown in the attached screen. They have to select one radio button in that column. The cellvalue of the grid must be retrieved from the database. Please clarify me how to create column wise choicelist.


Thanks in advance,
Pavith

Hi Pavithira,

You can get the desired behavior, by handling the CurrentCellChanged Event of the grid and try to set the cellvalue for other cells in the column to 1.

Here is a sample demonstrating this behavior

If I did not answer your question, please explain a little more about what you want, and I’ll try again.

Hi Haneef,

Thanks for your help.

I am having another doubt. If i click one radio button and unclick it, then it is working. But if i try to click the same button second time it is not working in the given sample. Please help me.

I am working in .Net2003. If u have any sample in .Net2003, please sent it to me.

Hi Pavithira,

Try this code snippet to resolve this.

int tristate = -1;
private void gridControl1_CurrentCellChanged(object sender, EventArgs e)
{
GridCurrentCell cc = this.gridControl1.CurrentCell;
if(cc.Renderer.StyleInfo.CellType == "RadioButton")
{
if(cc.Renderer.StyleInfo.CellValue.ToString() == "0")
{

int SelectedRowIndex = int.Parse(this.hs[cc.ColIndex].ToString());
if( SelectedRowIndex == cc.RowIndex)
this.gridControl1[cc.RowIndex,cc.ColIndex].CellValue = tristate = (tristate == 1)?0:1;
else
{
this.gridControl1[(int)(this.hs[cc.ColIndex]),cc.ColIndex].CellValue =1;
tristate = -1;
}
this.hs[cc.ColIndex] = cc.RowIndex;
}
}
}

Let me know if this helps.

Hi Haneef,

I need one more help. All are working fine. But if i set one radio button cell value as "0" during load event. Then if i try to click other one the previous one is also set to "0" that is both buttons are enabled.
Also i need one more clarification. I have attached a screen shot. Please have a look at it. The rows without radio button are filled with the number "1". I need to avoid that too. Please help me in this regard too.


Thanks,

Hi Pavithira,

You can handle the SaveCellInfo event and set the RowIndex of the selected radio button column. Below is a code snippet.

private void gridSaveCellInfo(object sender, Syncfusion.Windows.Forms.Grid.GridSaveCellInfoEventArgs e)
{
if(e.Style.CellType == "RadioButton" && IsLoad)
{
if( e.Style.CellValue.ToString() == "0" )
{
int SelectedRowIndex = int.Parse(this.hs[e.ColIndex].ToString());
if( SelectedRowIndex != e.RowIndex )
hs[e.ColIndex] = e.RowIndex;
}
}
}

bool IsLoad =true;
private void gridControl1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{IsLoad = false;}
