Hi,
I have a webimagebutton in my web page, in the Click event of this button i turn visible the grid, the datasource is taken by InitializeDataSource of the ultragridview, the dataset retorned have two datatables with a relation, this show me two bands levels in my ultrawebgrid; i wanna add a level from the second level band, but the image plus isn't visible.
The ultragridview is in a WebAsynchRefreshPanel, this warp have a TriggerControlId to the webimagebutton that i mentioned before.
Help me please, i need do it at this way, the data are too many to load them once.
Thanks,
Claudio G.
No reply????? ....please i need do this.
I made a new project to test, I created a table, i passing random values in a cycle to this table, after that, i give this table to the UltraWebGrid.DataSource property, and then, i do a UltraWebGrid.DataBind..., next I put the code, all this hapen in then InitializeDataSource of the grid:
but dont work, i steel dont see the plus image.
Thank you very much for your help.
'UltraWebGrid1_InitializeDataSource' is not supposed to be used under the binding mode. it's an improved and integrated Ajax-Engine. if you really need to use it,just to find some stuff about the page lifecycle of UltraWebGrid and 'invokeXmlHttpRequest'.for example:
on client side:function remote_request(gn) { var g = igtbl_getGridById(gn); var param=[; for (int i = 0; i < 21; i++){ param[param.length]=i + 1; } g.invokeXmlHttpRequest(g.eReqType.Custom, null, param.join(','))}
on server side: ...UltraWebGrid1_XmlHTTPRequest... If(e.Type==XmlHTTPRequestType.Custom ) { //do sth to read the submited param and and add the datarow one by one }
IMO,it's easier to use some standard ajax gallery to instead of 'UltraWebGrid1_XmlHTTPRequest',such as mootool,pototype...etc.
good luck.
Could you please post the code on how to call it on the aspx as well as code behind. What the events and how do we should the Expand + sign and place a FormView in the child.
Thanks
You might want to consider using the InitializeRow event, since it will fire for each row as it is bound, rather then the DataBound().
Awesome, thank you for posting this, it helped solved a problem I was not able to solve.
Thank you all people, i found a solution, a event of the grid, named DataBound. This is the sample code:
protected void UltraWebGrid1_DataBound(object sender, EventArgs e) { UltraWebGrid1.Bands.Add(new UltraGridBand()); foreach (UltraGridRow row in UltraWebGrid1.Rows) row.ShowExpand = true; }
And that's all, finally my grid show the plus image to open sub levels....
