RadGRid - How to apply fixed column width to some columns

Hi,
One of RadGrids in my application is having large number of columns. TableLayout of MasterTableView is "Fixed".
I have explicitly set width for each column so that when all columns are made visible, they all are displayed correctly.
But by default only few columns are visible and they are automatically expanded to cover whole width of the grid.
I do not want some columns like checkbox columns to expand. I want them to be always of fixed width.
How can I achieve this??

I know this can be achieved by not specifying width of one of the columns, but then that column width reduces to 0 when more number of columns become visible.

Thanks
Tushar

Three-State Checkbox - only two states when clicking?

Hello,

I added some three-state checkboxes like in the demo:

<telerik:RadButton ID="btnToggle" runat="server" ToggleType="CustomToggle" ButtonType="ToggleButton">

<ToggleStates>

<telerik:RadButtonToggleState Text="UnChecked" PrimaryIconCssClass="rbToggleCheckbox" />

<telerik:RadButtonToggleState Text="Filled" PrimaryIconCssClass="rbToggleCheckboxFilled" />

<telerik:RadButtonToggleState Text="Checked" PrimaryIconCssClass="rbToggleCheckboxChecked" />

</ToggleStates>

</telerik:RadButton>

This works fine, but I want to disable the "Filled" state when clicking.
I want to set all three states server-side, but the user shouldn't be able to use the "Filled" state - he should be able to just switch between "unchecked" and "checked".

How can I achieve this?

Thanks!

ItemStyle

Hi,
I am trying to visualize the fact that some dates are unavailable. I first tried to do this in Calendar_DayRender, but I was only able to disable the dates, not colorize them.

I then tried Calendar_PreRender, and added all unavailable dates (with formatting) into the calendars SpecialDays. What happened then was
1. still only disabled, no color.
2. when I go to next month, the backcolor appears. it then stays, and works ok.
3. ForeColor is never set. It seems that <span> overrides the styling. css for span is set by Telerik.

Any suggestions on how to fix this?

Avg in radgrid footer

Hello All,

I have activated Avg facility by applying Aggregate="Avg", which works fine but when the column is having no data then also avg counts that and calculates wrong avg.

for example

column1
$
$
$44
$44
$44
Avg: $26.40

Actually it should be $ 44

How to avoid blanks and How to achieve that?

Thank you!
Vishal

Select checkbox when textbox in grid clicked

I have a radgrid with a checkbox column and textbox column as follows:

this._RadGrid1.AllowFilteringByColumn = true;

this._RadGrid1.AllowSorting = true;

this._RadGrid1.MasterTableView.AllowNaturalSort = true;

this._RadGrid1.MasterTableView.DataKeyNames = new string[] { this._PriceDealProductBanTable.PriceDealEntityProductItemIdColumn.ColumnName };

this._RadGrid1.MasterTableView.ClientDataKeyNames = new string[] { this._PriceDealProductBanTable.PriceDealEntityProductItemIdColumn.ColumnName };

this._RadGrid1.EnableLinqExpressions = false;

this._RadGrid1.MasterTableView.NoMasterRecordsText = "No Products found.";

this._RadGrid1.MasterTableView.Width = Unit.Percentage(100);

this._RadGrid1.ClientSettings.Selecting.AllowRowSelect = true;

this._RadGrid1.AllowMultiRowSelection = true;

this._RadGrid1.NeedDataSource += RadGrid1_NeedDataSource;

this._RadGrid1.ItemDataBound += RadGrid1_ItemDataBound;

GridBoundColumn boundColumn = new GridBoundColumn();

string columnName;

#region RadGrid Columns

GridClientSelectColumn selectAll = new GridClientSelectColumn();

selectAll.UniqueName = "SelectOne";

this._RadGrid1.MasterTableView.Columns.Add(selectAll);

//Other columns

templateColumn = new GridTemplateColumn();

templateColumnName = this._PriceDealProductBanTable.BillingAccountNumberColumn.ColumnName;

this._RadGrid1.MasterTableView.Columns.Add(templateColumn);

templateColumn.DataField = templateColumnName;

templateColumn.ItemTemplate = new TextBoxTemplate(templateColumnName);

templateColumn.HeaderText = "BAN";

templateColumn.UniqueName = "BAN";

templateColumn.AllowFiltering = false;

The textboxtemplate is as follows:

public class TextBoxTemplate : ITemplate

{

protected RadTextBox _textBox;

string _columnName;

public TextBoxTemplate(string columnName)

{

this._columnName = columnName;

}

public void InstantiateIn(System.Web.UI.Control container)

{

this._textBox = new RadTextBox();

this._textBox.ID = this._columnName;

container.Controls.Add(this._textBox);

this._textBox.DataBinding += new EventHandler(_textBox_DataBinding);

}

void _textBox_DataBinding(object sender, EventArgs e)

{

RadTextBox txt = (RadTextBox)sender;

GridDataItem container = (GridDataItem)txt.NamingContainer;

txt.Text = ((DataRowView)container.DataItem)[this._columnName].ToString();

}

When I click on the textbox, I want the row to be automatically selected. How can I achieve this?
Also after selections are made, and i click on a row, all selections are disabled. I want to change this behaviour also. Deselect only happens when I click on the checkbox.

Change behavior of GridClientSelectColumn

I have a RadGrid as follows:

this._RadGrid1.AllowSorting = true;

this._RadGrid1.MasterTableView.AllowNaturalSort = true;

this._RadGrid1.MasterTableView.DataKeyNames = new string[] { this._PriceDealProductBanTable.PriceDealEntityProductItemIdColumn.ColumnName };

this._RadGrid1.MasterTableView.ClientDataKeyNames = new string[] { this._PriceDealProductBanTable.PriceDealEntityProductItemIdColumn.ColumnName };

this._RadGrid1.EnableLinqExpressions = false;

this._RadGrid1.MasterTableView.NoMasterRecordsText = "No Products found.";

this._RadGrid1.MasterTableView.Width = Unit.Percentage(100);

this._RadGrid1.ClientSettings.Selecting.AllowRowSelect = true;

this._RadGrid1.AllowMultiRowSelection = true;

this._RadGrid1.NeedDataSource += RadGrid1_NeedDataSource;

this._RadGrid1.ItemDataBound += RadGrid1_ItemDataBound;

GridBoundColumn boundColumn = new GridBoundColumn();

string columnName;

#region RadGrid Columns

GridClientSelectColumn selectAll = new GridClientSelectColumn();

selectAll.UniqueName = "SelectOne";

this._RadGrid1.MasterTableView.Columns.Add(selectAll);

the GridClientSelectColumn allows multiple selection, but clicking on a row de-selects all other rows. I want the all rows to stay selected unless manually de-selected from the checkbox. How can I achieve this?

[Solved] Displaying page index/counts

I put the following code in the RadGrid1_PageIndexChanged event:

if ((e.NewPageIndex + 1) == rgResults.PageCount)

{

showingRowsTo = GridSource.Tables[0].Rows.Count;

}

else

{

showingRowsTo = (e.NewPageIndex + 1) * rgResults.PageSize;

}

string rowCount = string.Format("Displaying {0}-{1} of {2}", showingRowsFrom, showingRowsTo, GridSource.Tables[0].Rows.Count);

lblResultsCountBottom.Text = lblResultsCountTop.Text = rowCount;

Unfortunately, it looks like this doesn't do a full postback and the label doesn't end up getting updated. How can I go about doing this? I tried doing it client side and had problems with this, too. It says $find is undefined.

$(document).ready(function () {

var grid = $find("<%=rgResults.ClientID%>");

var mtv = grid.get_masterTableView();

var pageIndex = mtv.get_currentPageIndex();

alert(pageIndex);

});

Suggestion on how to create vector image/pdf for chart on server side

Hi,

Can you please provide some suggestion on creating a chart on server side and export SVG out of it to create vector graphics/pdf.

We have an application which runs as a scheduler on the server, generates charts and emails them to customers in PDF/Images. All this without any manual interaction.

I looked at RadChart and RadHTMLChart. RadChart is a server side compontent but can't export vercor graphics, and RadHtmlChart renders SVG strictly the on browser.

The problem with using RadHtmlChart is we have to run a browser object from server side code to execute JS which can be a 'not so' reliable solution.

Please suggest. Thanks!
