如何使用Ajax dropdownextender的OnClientPopup通过javascript函数传递参数

Question

I'm developing an web user control using Ajax:dropdownextendeer and asp:controls .

I need to run a java-script function when user clicks on arrow of dropdownextender .

For that Ajax:dropdownextendeer provides an event OnClientPopup .

But this supports no parameters.I need to run a function that needs some parameters.

Is there any way to send parameters with OnClientPopup of Ajax:dropdownextendeer

Answer 1

Finally i got a solution for this problem. Ajax:dropdownextender doesn't support any parameters in java-script function on OnClientPopup .But we can pass parameters in java-script.Just add function on page load.

Ex.-

string func = "function docall(){showDataCombo('" + txtDisplay.ClientID
            + "','" + divGrid.ClientID
            + "','" + Table1.ClientID
            + "','" + txtSearch.ClientID
            + "','" + hfScrollPosition.ClientID
            + "','" + gridEdit.ClientID
            + "','" + lblTot.ClientID
            + "','" + Hidden_RowIndex.ClientID
            + "','" + divComboContainer.ClientID
            + "','" + DropPanel.ClientID + "');}";
        ScriptManager.RegisterClientScriptBlock(Page, this.GetType(), "CallJS", func, true);
        DDE.OnClientPopup = func;

Just create a function string without any parameters and call your java-script function in that.And assign this new function string on OnClientPouup event of Ajax-drop-downextender . And it works fine for me.
