Hello,

As I said before the event might be incorrect. My previous codes works fine. Even though I used only 2 Link WebCombo, when Edit item, WebCombo2 does not show the result based on the first row of WebCombo1.

Please review my attached sample. I bind using dsNorthwind in our WebCombo sample.

Regards,
Handy

Team,

Sorry that i am not in position to accept your sorry of delay....it got me in middle of no where....

Any how the sample you gave me will work if there are independent webcombos...

but if you look into my request and code carefull and watchfully the below line

Please provide your help for the same here is inner sample code for the bindings i am doing for in ItemDatabound Event of ListViewItem

and that code i shown was inside the event .....

---------------------------------------------------------------------

In that case when i tried to use initialise data source webcombos are not showing data but when i assign datasource in ItemDataBoundEvent then data is coming but again problem is linksetting which all rows are getting parentcombo from first row.

So I really appreciate your quick and resolving response

regards

Hello,

We are sorry for the late response. It seems your issue because incorrect binding life cycle. Our binding should be used in IntializeDataSource event. Please try to use your code in correct event.

Sample code:

 protected void WebCombo1_InitializeDataSource(object sender, DataSourceEventArgs e)
    {
        dsNorthwind.CategoriesDataTable dt = new dsNorthwind.CategoriesDataTable();
        dsNorthwindTableAdapters.CategoriesTableAdapter da = new dsNorthwindTableAdapters.CategoriesTableAdapter();
        da.Fill(dt);
        e.DataSource = dt;
        WebCombo combo = (WebCombo)sender;
        combo.DataTextField = "CategoryName";
        combo.DataValueField = "CategoryID";
        combo.LayoutSettings.ComboMode = Mode.MultipleColumns;
    }
 protected void WebCombo2_InitializeDataSource(object sender, DataSourceEventArgs e)
    {
        dsNorthwind.ProductsDataTable dt = new dsNorthwind.ProductsDataTable();
        dsNorthwindTableAdapters.ProductsTableAdapter da = new dsNorthwindTableAdapters.ProductsTableAdapter();
        da.Fill(dt);
        e.DataSource = dt;
        WebCombo combo = (WebCombo)sender;
        combo.DataTextField = "ProductName";
        combo.DataValueField = "ProductID";
        combo.LinkSettings.Enabled = true;
        combo.LinkSettings.FilterDataMember = "CategoryID";
        combo.LinkSettings.ParentWebComboID = "WebCombo1";
        combo.LayoutSettings.ComboMode = Mode.MultipleColumns;
    }

Please let me know your response.

Hi,

Scnario:

I have a listview and i am using 3 web combos combo1 , combo2 and combo3

combo2 is having link settings with combo 1

combo3 is having link settings with combo 2

combo4 is having link settings with combo 2

When i am bounding data with these combos in ItemDataBound of Listview item,

Problem:

Combos are loading properly and filters are running properly for first row. but for second row combo2,combo3 and combo4 are taking values of first row parent combos which is why its behaing differently than it should behave

Please provide your help for the same here is inner sample code for the bindings i am doing for in ItemDatabound Event of ListViewItem

WebCombo combo1 = new WebCombo();

WebCombo combo2 = new WebCombo();

WebCombo combo3 = new WebCombo();

WebCombo combo4 = new WebCombo();

rdPersonType = (RadioButtonList)e.Item.FindControl("uiRVRevieweTypeRD");

combo1 = (WebCombo)e.Item.FindControl("uiRVResponsibilityDDL");

combo2 = (WebCombo)e.Item.FindControl("uiRVDisciplineDDL");

combo3 = (WebCombo)e.Item.FindControl("uiRVPrimaryPersonDDL");

combo4 = (WebCombo)e.Item.FindControl("uiRVSecondaryPersonDDL");

combo1.DataSource = combo1datasource;

combo1.DataTextField = "tr_desc";

combo1.DataValueField = "tr_id";

combo1.DataBind();

combo2.DataSource = combo2datasource

combo2.DataTextField = "disc_desc";

combo2.DataValueField = "disc_id";

combo2.LinkSettings.Enabled = true;

combo2.LinkSettings.ParentWebComboID = combo1.ID.ToString();

combo2.LinkSettings.FilterDataMember = "tr_id";

combo2.LinkSettings.ParentEmptyAction = EmptyAction.ShowEmptyResult;

combo2.DataBind();

combo3.DataSource = combo3datasource;

combo3.DataTextField = "tech_person_primary_userid";

combo3.DataValueField = "tech_person_primary_userid";

combo3.LinkSettings.Enabled = true;

combo3.LinkSettings.ParentWebComboID = combo2.ID.ToString();

combo3.LinkSettings.FilterDataMember = "disc_id";

combo3.LinkSettings.ParentEmptyAction = EmptyAction.ShowEmptyResult;

combo3.DataBind();

combo4.DataSource = combo4datasource;

combo4.DataTextField = "tech_person_secondary_userid";

combo4.DataValueField = "tech_person_secondary_userid";

combo4.LinkSettings.Enabled = true;

combo4.LinkSettings.ParentWebComboID = combo2.ID.ToString();

combo4.LinkSettings.FilterDataMember = "disc_id";

combo4.LinkSettings.ParentEmptyAction = EmptyAction.ShowEmptyResult;

combo4.DataBind();
