Custom Filter with Filter options based on visible entries

hi ,

not sure if this is the right place to post this but i thought it might be useful for people , i implemented the custom Google Style filter , as per the example given , but i have found a way to extend it , so the filter options are based on the current visible results in the grid , i.e if you have allready put another filter in place , it limits the filter results in the other columns based on the results on the previous filters.

here is the code for it.

public class MyGenericFilter : GridBoundColumn

{

//RadGrid will call this method when it initializes the controls inside the filtering item cells

protected override void SetupFilterControls(TableCell cell)

{

base.SetupFilterControls(cell);

cell.Controls.RemoveAt(0);

RadComboBox combo = new RadComboBox();

combo.ID = ("RadComboBox1" + this.UniqueName);

combo.ShowToggleImage = false;

combo.Skin = "Office2007";

combo.EnableLoadOnDemand = true;

combo.AllowCustomText = true;

combo.AutoPostBack = true;

//combo.MarkFirstMatch = true;

combo.Height = Unit.Pixel(100);

combo.Width = Unit.Pixel(100);

combo.ItemsRequested += this.list_ItemsRequested;

combo.SelectedIndexChanged += this.list_SelectedIndexChanged;

combo.DropDownWidth = Unit.Pixel(150);

cell.Controls.AddAt(0, combo);

//cell.Controls.RemoveAt(1);

}

//RadGrid will cal this method when the value should be set to the filtering input control(s)

protected override void SetCurrentFilterValueToControl(TableCell cell)

{

base.SetCurrentFilterValueToControl(cell);

RadComboBox combo = (RadComboBox)cell.Controls[0];

if ((this.CurrentFilterValue != string.Empty))

{

combo.Text = this.CurrentFilterValue;

}

//RadGrid will cal this method when the filtering value should be extracted from the filtering input control(s)

protected override string GetCurrentFilterValueFromControl(TableCell cell)

{

RadComboBox combo = (RadComboBox)cell.Controls[0];

return combo.Text;

}

private void list_ItemsRequested(object o, RadComboBoxItemsRequestedEventArgs e)

{

((RadComboBox)o).DataTextField = this.DataField;

((RadComboBox)o).DataValueField = this.DataField;

RadGrid MyGrid = ((RadGrid)((RadComboBox)o).Parent.Parent.Parent.Parent.Parent.Parent);

MyGrid.AllowPaging = false;

MyGrid.Rebind();

DataTable NewDT = new DataTable(this.DataField);

NewDT.Columns.Add(new DataColumn(this.DataField));

foreach (GridDataItem GD in MyGrid.Items)

{

if (GD[this.DataField].Text.Contains(e.Text) && GD[this.DataField].Text != " ")

{

var foundAuthors = NewDT.Select(this.DataField + " = '" + GD[this.DataField].Text + "'");

if (foundAuthors.Length == 0)

{

DataRow DR = NewDT.NewRow();

DR[this.DataField] = GD[this.DataField].Text;

NewDT.Rows.Add(DR);

}

MyGrid.AllowPaging = true;

MyGrid.Rebind();

NewDT.DefaultView.Sort = this.DataField + " ASC";

((RadComboBox)o).DataSource = NewDT;

((RadComboBox)o).DataBind();

}

private void list_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)

{

GridFilteringItem filterItem = (GridFilteringItem)((RadComboBox)o).NamingContainer;

if ((this.UniqueName == "Index"))

{

//this is filtering for integer column type

filterItem.FireCommandEvent("Filter", new Pair("EqualTo", this.UniqueName));

}

//filtering for string column type

filterItem.FireCommandEvent("Filter", new Pair("Contains", this.UniqueName));

}

Possible to change the PrimaryIconCssClass or PrimaryIconUrl properties from client side?

Hello,

I have a scenario that requires me to change the image on a particular RadButton from javascript. Is this possible? It is easy to change the text using the "set_text" function but changing the Image doesn't seem to be possible directly using the api.

Any help would be appreciated.

Thanks,
Ben

Issues when SeoPaging is integrated

Hi!
I've a listview (with dropdownlists used as filters). Everything is working fine until SeoPaging is integrated.

First the "prev - next, ..." buttons dissapears (image not found logo replace the initial buttons images) even if I set : NextPageImageUrl="\Images\buttons\next.jpg" LastPageImageUrl="\Images\buttons\last.jpg" in radatapager properties.

I tried doing that as explain in this forum:

<script type="text/javascript">

function pageLoad() {

var pager = $find('<%=RadListView1.FindControl("RadDataPager1").ClientID %>').get_element();

$telerik.$(pager).find(".rdpWrap a img")[0].src = "PagingFirst.gif";

$telerik.$(pager).find(".rdpWrap a img")[1].src = "PagingPrev.gif";

$telerik.$(pager).find(".rdpWrap a img")[2].src = "PagingNext.gif";

$telerik.$(pager).find(".rdpWrap a img")[3].src = "PagingLast.gif";

}

</script>

But is says Cannot call method 'get_element' of null
...

Second: When SeoPaging is enabled, I lost the filters on page change. For instance I have my listview with all data, when I apply a filter, it will do it correctly but when I click on page 2, it will go page 2 but all data will be back and the filter is forget...

Any idea how to solve this?

Thanx in advance

RadGrid filtering with backslash

Hi,

I have a RadGrid bound server-side to a DataTable and in a RadAjaxManager and a filter on a GridBoundColumn with string values.

The filter works fine except when I search for a backslash '\'. When escaped "\\" the filter works.

I looked at you basic filter sample (http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/filtering/defaultcs.aspx)

and it seems this filter doesn't work there either.

Is there a workaround this?

Thank you

Nikoleta

Launching the RadWindow

Hello,

I am using the rad window for the first time. Here is the code, how I have declared rad window.

<telerik:RadWindowManager ID="RadWindowMyImage" runat="server" EnableShadow="true">
<Windows>

<telerik:RadWindow ID="RadWindow1" runat="server" Modal="true">
<ContentTemplate>
<placeholder id="iframe1" runat="server" width="400px" height="400px">
</placeholder>
</ContentTemplate>
</telerik:RadWindow>
</Windows>
</telerik:RadWindowManager>

and I am loading an image and launching the window like this.

PlaceHolder mybox = RadWindow1.ContentContainer.FindControl("iframe1") as PlaceHolder;
System.Web.UI.WebControls.
Image appImage = new System.Web.UI.WebControls.Image();
string base64String = Convert.ToBase64String(myimage, 0, myimage.Length); //myimage is byte array
appImage.ImageUrl = "data:image/png;base64," + base64String;
appImage.Width = Unit.Pixel(100);
appImage.Height = Unit.Pixel(100);
iframe1.Controls.Add(appImage);
RadWindow1.Visible = true;

Am I doing correctly?? My rad window is not getting poped up when I click the button. Can any one help me out in this? Where I am doing wrong?

Thanks in Advance.

Thanks,
Geetha Rani.
