- ASP.net GridView - OnCommand not fired! - ASP.NET Discussion Boards

can you please explain a bit about the modified query.

Example:
========
Actual query is,

select column1, column2, column3 from table1

Imagine you want to add columns in between 1 and 2, 2 and 3 then the query should be,

select column1, '' as tempcol1, column2, '' as tempcol2, column3 from table1

then on the itemdatabound event you can add any control like (button, linkbutton, or dropdownlist) on the column

Explanation:
============
You just execute the these two queries. First query will return three columns, second query will return five columns. The temp columns are not available in any table, which will be used to create a column in the grid. You just execute this queries in the query analyzer and check.

Hi,

I have a problem with event on LinkButton inside my TemplateField of GridView which is programmatically created.
When I create GridView's TemplateField, I use special class that inherits from ITemplate.
In this class I try to create LinkButton for every row of GridView.

This is my code:

class GridViewTemplate : System.Web.UI.Page, ITemplate<br />
    {<br />
        ListItemType templateType;<br />
        string columnName;<br />
<br />
        void ITemplate.InstantiateIn(System.Web.UI.Control container)<br />
        {<br />
            switch (templateType)<br />
            {<br />
                case ListItemType.Item:<br />
                    LinkButton lbtn = new LinkButton();<br />
                    lbtn.DataBinding += new EventHandler(Object_DataBinding);<br />
                    lbtn.CssClass = "TextBlackBold";<br />
                    lbtn.Command += new CommandEventHandler(this.TakeTaskLinkButton_OnCommand);<br />
                    lbtn.CommandName = "SubmitTakeTaskLinkButtonCommandName";<br />
                    container.Controls.Add(lbtn);<br />
                    break;<br />
            }<br />
        }<br />
<br />
        void Object_DataBinding(object sender, EventArgs e)<br />
        {<br />
            LinkButton lbtn = (LinkButton)sender;<br />
            GridViewRow container = (GridViewRow)lbtn.NamingContainer;<br />
            lbtn.ID = "TakeTaskLinkButton" + DataBinder.Eval(container.DataItem, "taskid").ToString();<br />
            lbtn.Text = DataBinder.Eval(container.DataItem, "tasktitle").ToString();<br />
            lbtn.CommandArgument = DataBinder.Eval(container.DataItem, "taskid").ToString();<br />
        }<br />
<br />
        void TakeTaskLinkButton_OnCommand(object sender, CommandEventArgs e)<br />
        {<br />
            switch (e.CommandName)<br />
            {<br />
                case "SubmitTakeTaskLinkButtonCommandName":<br />
                    Response.Redirect("Default.aspx");<br />
                    break;<br />
            }<br />
        }<br />
<br />
        public GridViewTemplate(ListItemType type, string colName)<br />
        {<br />
            templateType = type;<br />
            columnName = colName;<br />
        }<br />
    }

and the TakeTaskLinkButton_OnCommand method is not fired when I click on the LinkButton.
I don't know why!? Any suggestions? How can I solve this problem?

Regards,

(Sorry for any mistakes)

hello

i'm making a appliocation in asp.net with vb.

i have to use PayPal and 2checkout.com for Payment.I have already downloaded the Paypal component for Asp.Net but i'm getting how to use it.

We hav Four Plans.for 1$, 3$,5$,7$. I just Want when any user choose any plan then he can can pay the payment through the Above Method and I have to keep the Account or Information that which user have paid the money or not.

Plz Guide me in this matter.

thanx

I'd recommend maybe having a wee look at the PayPal site. They must have some information there on how to do this...

Yes paypal has got .net SDK which can be use to connect to paypal server and do all the validation.

hello thanx for reply
i have download the SDk but not getting how to use.
i have seen some of the example too.
but they were not very useful to me.
what i have to do just pay the payment after calculation.
in my website there is no such Add to Cart Like thing.
user just can click on the plan and for how many month he want this plan.
suppose one plan cost is 1$ for a month.if he select For 2 Month.then total amount is 2$.
now how to payment this 2$ using paypal.
if u hav some REF: Code then plz send me if possible otherwise guide me.
thanx
i will wait for ur reply.

Hi,
So you want a code that will send credit card number and others details and verifiy and tell you if valid or not.
check this link and download the sample of paypal with asp.net. I have the functionality of adding to cart but can just ignore the cart functionality and check how credut card validation and verfication is done.
hope it helps.
If time permit I will send you a sample for this validation.
Regards,
Anil

hello

hi this is my problem

every time i click on my change my drop down list the pageload is activated once

so i though about putting something inside this function so that when i change the select something from the drop down list the pageload wont be activated

private void DropDownList1_SelectedIndexChanged(object sender, System.EventArgs e)
{
}

can any one giv me the code or some method to solve tis please >.<

private void Page_Load(object sender, System.EventArgs e)<<===the header of my pageload

thx you in advance =)

You might like to check for this.IsPostBack in page load event handler before you do anything in pge load.

- ashish

Hi,

u may need to set the AutoPostBack Property of the DropDownList control to "False", in order to avoid Page_Load event occurs every time u change the value in ur DropDownList.

Hope it works..

Jay
