Grouping Persist Expand Collapse State without ViewState

The Example of keeping the expanded/collapse state of groups that Telerik provide uses the viewstate. If you have viewstate disabled, it causes a few kinks. Since I had to write this myself, I figured I'd share in case anyone needed it.

These two were in a class call telerikhelpers but you could put them anywyere

/// <summary>

/// this loads the saved states of the group headers

/// (whether they were collapsed or expanded) you have to pass in the

/// grid you want to bind

/// </summary>

/// <param name="grid">the grid you want to bind</param>

public static void LoadGroupsExpandedState(RadGrid grid)

{

var listCollapsedIndexes = HttpContext.Current.Session[grid.ID] as ArrayList;

if (listCollapsedIndexes != null)

{

foreach (GridItem item in grid.MasterTableView.GetItems(GridItemType.GroupHeader))

{

if (listCollapsedIndexes.Contains(item.RowIndex))

{

item.Expanded = false;

}

}//LoadGroupsExpandedState

/// <summary>

/// this function sets a session variable to remember which grouping items have been

/// collapsed or expanded

/// </summary>

/// <param name="grid"></param>

/// <param name="curItem"></param>

public static void SaveGroupsExpandedState(RadGrid grid, GridItem curItem)

{

GridItem[] groupItems = grid.MasterTableView.GetItems(GridItemType.GroupHeader);

if (groupItems.Length > 0)

{

var listCollapsedIndexes = new ArrayList();

//if this first one is true, then we need to add it to the list

//basically the state that is getting passed in is the old state

//so if it's expanded = true, then it was expanded, and it's

//getting collapsed

if (curItem.Expanded)

{

listCollapsedIndexes.Add(curItem.RowIndex);

}//if curItemExpanded

else

{

//check if it's in the list

if (listCollapsedIndexes.Contains(curItem.RowIndex))

{

listCollapsedIndexes.Remove(curItem.RowIndex);

}//if listCollapse

}//else

foreach (GridItem item in groupItems)

{

if (!item.Expanded && item.RowIndex != curItem.RowIndex)

{

listCollapsedIndexes.Add(item.RowIndex);

}

HttpContext.Current.Session[grid.ID] = listCollapsedIndexes;

}

}//SaveGroupsExpandedState

Then attach these two functions to your itemdatabound and databound events on the acutal grid itself

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)

{

//get the grid

RadGrid grid = sender as RadGrid;

//if this is expand or collapse, save the state

if (e.CommandName == RadGrid.ExpandCollapseCommandName)

{

TelerikHelpers.SaveGroupsExpandedState(grid, e.Item);

}

}//ItemCommand

/// <summary>

/// This method adds logic on how to handle a databound (restore the grouping set on screen)

/// </summary>

///The parameter is not used.

protected void RadGrid1_DataBound(object sender, EventArgs e)

{

TelerikHelpers.LoadGroupsExpandedState(sender as RadGrid);

}

If you make the first two accessible globally, you can literally attach multiple grids on a page to the same databound and item command events and it will just work. Hope this helps someone else!

ExcelML Line Breaks

There are a few old threads up here - one from 2008 or 2009 stating that the RadGrid ExcelML export does not support line break characters. Is this still the case?

I have a few cells that have line breaks I would like to bring through the ExcelML export - and have tried several approaches, but no luck.

Is this still an unsupported scenario?

Volume Bar and ProgressRail doesn't work in IE11

I'm watching the demo "MediaPlayer - Video Gallery" (http://demos.telerik.com/aspnet-ajax/media-player/examples/applicationscenarios/video-gallery/defaultcs.aspx), in the RadLightBox pop up the volumen bar and the progressrail bar didn't work. I'm using IE 11.

I'm built my own webapp and I found the same problem.

Collapse/Expand all in RadGrid

I've got a RadGrid on my page with one level of DetailTables. Each detail table has a chevron next to it that collapses that table. I'd like to have a chevron on the master table that expands or collapses all the detail tables (if any are expanded, it collapses them all; otherwise, it expands them all). Is this a setting that can be set? I would rather have the same look and feel, rather than using a button to expand or collapse all the tables.

Problem with expand/collapse of grid grouping.

Hi.

My requirement is for a grid that will be dynamically populated,
Because of this I build the entire grid in my code behind.

I have this 99% working except for this issue with grouping:

When I group by a column and expand the group, then collapse the same group again it will collapse without any problem.

I also have these tabs which is essentially just a string value that I pass in from a hidden field it can optionally be used as a filter when I bring back a search result that will populate my grid.

The problem come in when I pass in this string; I am able to expand any of my groups, but when I want to collapse the group the page posts back but does not collapse the group again.

protected void Page_Init(object sender, System.EventArgs e)

{

string filterValue = HorizontalTabFilter();

string verticalFilterValue = VerticalTabFIlter();

boundColumn.DataField = "ABSTRACTLINK";

boundColumn.HeaderText = "ABSTRACTLINK";

boundColumn.Visible = false;

this.PlaceHolder1.Controls.Add(grid);

}

On page Page_Init I use DefineGridStructure(); to build my grid and bind the datatable that comes from ed.SearcheDOCS(selectedTab, selectedVerticalTab, selectedVerticalTabIndex);

Then depending on the number of columns returned I build the grid,
when one of these filter values I mentioned above is passed in while grouped I use the code below, so when it posts back to collapse after having been expanded the code runs as expected but will not collapse the expanded group.

if (selectedTab != "" || selectedVerticalTab != "")

{

grid.DataSource = null;

grid.Rebind();

} grid.DataSource = dt = ed.SearcheDOCS(selectedTab, selectedVerticalTab, selectedVerticalTabIndex);

I could really use some help with this.

Any ideas?

[Solved] Does anyone know if this layout still exists?

I'm currently upgrading Telerik for our company, however it looks like the combo box layout that we used to use isn't there anymore.

I was hoping we would have the images that were used here, however it looks like we are missing those.

Attached is a screenshot of the combobox that we are using.

PivotGrid slow to render on IE10

The PivotGrid on my webpage is running very slowly when using Internet Explorer 10. However, the performance is greatly improved when using Firefox instead.

As Internet Explorer 10 is part of my company's SOE, is there anything that can be done to improve the performance of the PivotGrid when using IE10 as the browser?

Hiding Caption in Export to Excel

Hello,

I have many radgrids in my solution & most of them have export to excel feature implemented. Recently, we added Summay & Caption Statements to these grids in the ASPX files. In order not to show the Captions when the grid is displayed, I added a CSS class like "rgCaption" or "MasterTable_Default caption" or "DetailTable_Default caption".

Here is the example of the class.

.rgCaption
{
position: absolute;
left: -10000px;
top: auto;
width: 1px;
height: 1px;
overflow: hidden;
visibility: hidden;
line-height: 0;
}

So when the grid is displayed in the webpage, the caption is hidden. I also want to do something similar when I do the export to excel (using CSS). Currently all my exported excels show the Caption which I don't want. I can always say Grid.MasterTable.Caption = String.Empty() in OnExcelExportCellFormatting or OnGridExporting. But this approach would make me edit all of the pages where export is involved & is too tedious & time-taking. I also tried

Any Ideas?

Thanks
